Abstract
A novel cyclobutenedione-containing poly(phenylenevinylene) (PPV) was obtai ned from 3,4-bis(4-bromomethylphenyl)-3-cyclobutene-1,2-dione via modified 1, 12-polydehydrohalogenation. This resultant polymer, soluble in polar apr otic solvents, exhibits a regioregular structure of alternating cis- and tr ans-vinylene units. The present polymer exhibits photoluminescence with a m aximum at 472 nm, corresponding to the blue emission region, in DMAc soluti on, and a red-shift emission at 574 nm in the film.
