A novel cyclobutenedione‐containing poly(phenylenevinylene) (PPV) was obtained from 3,4‐bis(4‐bromomethylphenyl)‐3‐cyclobutene‐1,2‐dione via modified 1,12‐polydehydrohalogenation. This resultant polymer, soluble in polar aprotic solvents, exhibits a regioregular structure of alternating cis ‐ and trans ‐vinylene units. The present polymer exhibits photoluminescence with a maximum at 472 nm, corresponding to the blue emission region, in DMAc solution, and a red‐shift emission at 574 nm in the film.
