Abstract
The synthesis of substituted poly(p‐phenylenenvinylene) (PPV) was carried out via metathesis polycondensation of 2,5‐diheptyl‐1,4‐divinylbenzene (DHepDVB). A stable molybdenumcarbene complex served as catalyst. The preparation of the educt employed (DHepDPV, 3a) is described. The obtained poly(2,5‐diheptyl‐1,4‐phenylenevinylene) (DHepPPV, 5), an intensely yellow product, has an all‐trans‐configuration and, with a degree of polymerization of ≈ 10 is soluble in conventional organic solvents.Keywords
