New Schiff’s base (ligand) and its copper, cobalt, nickel and zinc metal ion complexes were synthesized with a good yield of 86 to 68.9%. and characterized by various anal. techniques. The spectral data confirms the formation of the compounds The ligand and the metal complexes were screened for anticancer activities with A549 and H1299 lung cancer lines. The results indicated that the zinc metal ion complex was the most active with 83.60 and 88.52% inhibitions for A549 and H1299 lung cancer lines at 20 mM concentration Besides, DNA binding study confirmed good binding constants (0.94 x 105-2.31 x 105) with a maximum of zinc metal ion complex (2.31 x 105); confirming the anticancer activities results. The docking study also confirmed that the reported mols. interacted with DNA strongly by hydrogen bonding and hydrostatic interactions with -4.6 kCal/mol as binding energy. It was also observed that the reported mols. preferred minor grooves of DNA for interactions. The excellent anticancer activities of metal complexes confirmed that these complexes may be the future lung cancer medication.

Doi, Marina published the artcilePhotoluminescence properties of copolyimides containing naphthalene core and analysis of excitation energy transfer between the dianhydride moieties, Name: 4,4-Diaminodicyclohexyl methane, the publication is Journal of Photopolymer Science and Technology (2021), 34(5), 423-430, database is CAplus.

The photoluminescence (PL) properties of semi-aromatic polyimide (PI) films and their model compounds (MCs) prepared from dianhydrides having a rigid naphthalene core were analyzed. The PMMA-dispersed MC and copolymerized PI (CoPI) films derived from 2,3,6,7-naphthalenetetracarboxylic dianhydride (NTDA) exhibited long-lived phosphorescence owing to the suppression of mol. motion by the rigidity of a naphthalene core. Addnl., the PMMA-dispersed MC and the CoPI films derived from 1,5-dibromo derivative of NTDA (DBrNT) exhibited room-temperature phosphorescence due to the enhancement of spin-orbit coupling by bromine atoms. The photophys. processes of the CoPI films prepared from NTDA/DBrNT and 4,4′-oxydiphtalic dianhydride (ODPA) in which the latter absorption band is located at a shorter wavelength than the former were analyzed. After UV irradiation, efficient excitation energy transfer occurs from the ODPA to NTDA/DBrNT moieties, and only the emission from the latter moieties was observed These results demonstrate that the CoPI films derived from two dianhydrides absorbing different UV wavelengths can be used as spectral conversion films that convert a wide range of UV-light into longer wavelength visible light.

Rahimi, AliReza published the artcileAmphiphilic marine coating systems of self-stratified PDMS-PEG surfaces with an epoxy-polyurethane matrix, Computed Properties of 1761-71-3, the publication is Journal of Coatings Technology and Research (2022), 19(3), 795-812, database is CAplus.

Marine coatings protect submerged surfaces from the neg. effects of biofouling. In this work, we demonstrate a new method to prepare self-stratified, amphiphilic glycidyl-carbamate (GC)-based (epoxy urethane-based) coatings (AmpSiGC coatings) that have fouling-release properties making them suitable for marine use. The prepared coating systems are unique and durable in character as the bulk coating takes advantage of both epoxy and urethane functionalities while the surface is comprised of both hydrophilic and hydrophobic domains, granting it an amphiphilic characteristic. The exptl. approach aimed to evaluate several factors that influence coating performance, including mol. weight of poly(ethylene glycol) (PEG) and PDMS moieties, ratio of hydrophobic (PDMS) and hydrophilic (PEG) components in the system, and the effect of different curing agents. The results demonstrated that polymeric chains of 10,000 M_n PDMS and 750 M_n PEG at 10-15 weight% each offer substantially improved or comparable fouling-release performance in comparison to com. marine coatings. This paper reports on the facile synthesis and characterization of the GC resin and GC prepolymers using FTIR and epoxy titrations; surface characterization of the coatings using ATR-FTIR, XPS, and AFM; and fouling-release assessment of the surfaces using laboratory biol. assays with the barnacle Amphibalanus amphitrite, the algae Ulva linza and Navicula incerta, and the bacteria Cellulophaga lytica. Several of the AmpSiGC coatings exhibited promising performance, which were better or comparable to the internal and com. reference coatings. The performance of the systems was dependent on all of the factors considered in this study.

Cuypers, Thomas published the artcileNi-Catalyzed reductive amination of phenols with ammonia or amines into cyclohexylamines, Product Details of C13H26N2, the publication is Green Chemistry (2020), 22(6), 1884-1893, database is CAplus.

Phenol and its derivatives, which naturally occur in lignocellulose, can be considered as a renewable feedstock not only for aromatic, but also for alicyclic compounds, such as primary and N-substituted cyclohexylamines. So far, the latter are mostly produced from non-renewable starting materials like benzene via problematic nitration/reduction or cross-coupling routes. Herein, an efficient reductive amination of phenol with ammonia or amines is demonstrated, for the first time without the need for rare and expensive noble metals and without using any additives. Various supported Ni catalysts were screened and we elucidated the influence of the key parameters, including the acid-base properties of the supporting material. Acquired knowledge was then applied to different phenol-ammonia/amine combinations, resulting in the synthesis of various primary, secondary and tertiary cyclohexylamines in fair to very high yields.

Duan, Jiang published the artcileDisilyl Bis(Secondary Amine)-Enabled Epoxy Ring-Opening and Silylotropic N → O Migration Leading to Low Dielectric Epoxy Copolymers, HPLC of Formula: 1761-71-3, the publication is Macromolecules (Washington, DC, United States) (2021), 54(14), 6947-6955, database is CAplus.

This work presents a strategy for fabricating low dielec. epoxy copolymers through copolymerizing bisphenol A diglycidyl ether with N,N’-disilyl bis(secondary amine)s, a series of difunctional silylamines synthesized by silylation of bis(secondary amine)s. A study on the model reaction of monoepoxy with monofunctional silylamines identified that the reaction proceeded smoothly in THF with Mg(ClO₄)₂ catalysis and mechanistically through sequential silylamine-induced epoxy ring-opening and silylotropic N → O migration, a process with favorable Gibbs free energy changes as confirmed by d. functional theory calculations The copolymers demonstrated remarkably low dielec. constants and dielec. losses due to the formation of the low-polarizable silyloxyl instead of the hydroxyl group in polymerization and the enlarged mol. free volume In addition, the copolymers showed desirable toughness, hydrophobicity, and thermal stability. As a tool to achieve these desirable features, the strategy developed in this work may find promising application in designing low dielec. epoxy resin materials for use in the microelectronic field.

Beyer, Frederick L. published the artcileApplication of the small-angle scattering invariant to morphological behavior in ballistic materials, Recommanded Product: 4,4-Diaminodicyclohexyl methane, the publication is Journal of Applied Polymer Science (2021), 138(21), 50478, database is CAplus.

The small-angle scattering invariant provides a useful tool for quantifying nanoscale morphol. features in two-phase materials, when scattering data of sufficient quality and angular range are available. In this work, an invariant anal. has been performed on small-angle X-ray scattering data for a series of epoxy-amines previously found to have relatively high-energy absorption (KE50) in ballistic impact tests. The improved performance was hypothesized to be a result of the formation of an ill-defined two-phase morphol., observed but not quantified using transmission electron microscopy. In this anal., the ballistic performance and the scattering invariant were found to be strongly correlated, with a Pearson’s linear correlation coefficient of 0.94. Facile anal. enabled by a custom software procedure suggests that this previously difficult anal. may be more broadly useful, even in high throughput applications.

Zhou, Zhuxin published the artcileAchieving white-light emission in a single-component polymer with halogen-assisted interaction, Application of 4,4-Diaminodicyclohexyl methane, the publication is Science China: Chemistry (2021), 64(3), 467-477, database is CAplus.

White-light emitting (WLE) polymers have attracted continuous attention for their promising applications in solid-state lighting, flexible display and related fields. However, achieving dual-emission and pure white-light emission in a single-component polymer is still challenging. In this study, a brominated single-component polymer BrOD-TFB was designed and synthesized, which shows dual-emission and white light emission properties in solution and room-temperature phosphorescence (RTP) in thin films. The dual-emission properties can be tuned by concentration, solvent polarity, and excitation energy. Spectral anal. and theor. calculations reveal that the origin of the high-energy emission band (HEB) is intramol. charge transfer (ICT) along the polymer chain, while the low-energy emission band (LEB) originates from the excited-state related to the intra-chain and inter-chain C-Br···π interactions as demonstrated by the single-crystal structure of the model compound Appropriate control of the formation and the destruction of the halogen-assisted interactions can initiate white-light emission in the single-component polymer. More interestingly, by dispersing BrOD-TFB (0.1 wt%) in a non-emissive, colorless and transparent polymer, the characteristics of this white-light emission can be fully demonstrated while exhibiting unexpected RTP properties, with photoluminescence quantum efficiency (φ_PL) of up to 23% and CIE coordinates of (0.32, 0.32).

Asemani, H. R. published the artcileDual-curable coatings obtained from multi-functional non-isocyanate polyurethane oligomers, Related Products of quinuclidine, the publication is Journal of Coatings Technology and Research, database is CAplus.

The growing concerns and impending regulations on the usage of monomeric isocyanates in the production of polyurethane resins have led to the introduction of alternative non-isocyanate polyurethane (NIPU) systems. Although two-component NIPU coatings based on the reaction of cyclic carbonates and aliphatic amines have emerged as a promising option, they are still associated with two significant drawbacks: lower crosslinking densities due to reduced functionality of the oligomers and low ambient-temperature reactivity. This study reports the utilization of a hybrid approach to address these drawbacks. Amine-functional NIPU oligomers (NI-PUPA) were synthesized by the reaction of cycloaliphatic amine functional compounds and multi-functional cyclic carbonates in an excess amine molar ratio. After mixing the NI-PUPAs with (3-glycidyloxypropyl) trimethoxysilane (GPTMS), a dual-curable coating could be achieved by ambient curing of amines and epoxies and moisture curing of alkoxy silanes. A comparative exptl. design was implemented to evaluate the effect of an addnl. curing mechanism. The results revealed that the addnl. moisture curing led to faster ambient curing, faster development of properties, enhanced flexibility even at higher crosslinking densities, and better corrosion resistance. Such advancement could facilitate the future implementation of NIPUs in high-performance ambient-curing coating applications.
