Description
Summary: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.
