A new class of photorefractive polymers based on poly(1,6-heptadiyne) derivatives have been synthesized by metathesis cyclopolymerization of 1,6-heptadiyne derivatives containing a carbazole unit and a NLO chromophore. These polymers have a long tail band at above 700 nm. Also, these polymers show two maximum values of photocurrent around 350 and 700 nm.
