Abstract

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°C and 130°C. Luminescence studies on some of the coumarin-containing polymers (CCPs) showed some fluorescence [φF 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.
