Abstract

A novel coumarin‐containing monomer 6‐[4‐acetoxyphenyl]coumarin‐3‐carboxylic acid (5) was prepared and characterized. It was copolymerized by high‐temperature polycondensation with m‐acetoxybenzoic acid (11) to give copolymers with M~n~ of 5 300–18 000, soluble in common organic solvents and containing up to 40 mol‐% of monomer 5. All copolymers were amorphous, with T~g~ increasing with monomer 5 ratio (from 147 to 162°C) and high optical quality films preparable by solution casting from chloroform. All polymers show strong photoemission in the blue‐green region and some of them present electroluminescence.

## Abstract Two novel coumarin‐containing monomers, 3,3′‐bis(ethoxycarbonyl)‐6,6′‐bicoumarin (3) and 7‐[(2‐norbornenyl)methoxy]coumarin (7), were prepared and characterized. They give polymers with __M__~w~ up to 350 000 and are soluble in common organic solvents. Polymers were prepared by high tem
