Abstract
Two novel curing agents N-((4-(12-(4-(o-hydroxyphenylimino) methyl)phenoxy)dodecanyl-oxy)benzylidene)-2-hydroxybenzenamine) and N-((4-(12-(4-(p-hydroxyphenylimino)methyl)phenoxy)-dodecanyloxy) benzylidene)-4-hydroxybenzenamine) were synthesized and characterized by FTIR and NMR spectral analysis. A series of novel polymers were obtained via curing reaction of epoxy resin. The characterization of the thermosets was performed by FTIR spectral analysis. The photo-physical properties of the synthesized thermosets were evaluated by UV–Vis and photoluminescence spectral analyses. All the thermosets absorbed in the UV region (271–281 nm), which is attributed to the CH=N in conjugation with phenol moieties, incorporated into polymer network. Thermoset based on the synthesized curing agents emitted light in the blue region, which is attributed to the azomethine linkage in polymeric thermoset. Thermal stability and light emissive properties of the new polymer systems suggested their future use as a blue light emissive, thermally resistant adhesives.
期刊介绍：
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
