Abstract
A number of luminescent polymeric Schiff bases were prepared by conden sation polymerization of luminophoric diamines with aromatic dialdehyd es in N-methylpyrrolidone. Specific features of the synthetic procedur e as affected by the nature of the starting reagents were examined. Th e absolute quantum yield of polymer solution luminescence was measured , and the glass transition temperatures were calculated for all the po lymers synthesized. The luminescence efficiency of polymer solutions w as found to directly correlate with the glass transition temperature o f the polymers, which may be regarded as a measure of the chain stiffn ess.
