Benzo[f]- and Benzo[h]Coumarin-Containing poly(methyl methacrylate)s and poly(methyl methacrylate)s with pendant coumarin-containing azo dyes

摘要

A series of coumarins were reacted with methacrylate or styrene derivatives to form new olefinic coumarin monomers that were polymerized using 2,2'-azoisobutyronitrile (AIBN). These polymers were highly insoluble in organic solvents and displayed good thermal stability with glass-transition temperatures between 70 degrees C and 130 degrees C. Luminescence studies on some of the coumarin-containing polymers (CCPs) showed some fluorescence (Phi(F) around 0.1). Some of the newly-prepared coumarins and benzocoumarins were reacted with azo dyes to form mixed coumarin-azo dye complexes. These mixed complexes were further reacted to prepare acrylic monomers and polymerized using AIBN. These polymers were thermally stable and poorly soluble in organic solvents.
