Abstract
The synthesis of unsubstituted meta– para oligo-phenylenevinylene ( mp-OPV) was carried out via metathesis polycondensation (acyclic diene metathesis polymerisation ADMET) of commercially available divinylbenzene (55% in ethylvinylbenzene). A stable molybdenum carbene complex of the Schrock type served as initiator. The obtained mp-OPV, which is an intensively yellow powder, with a degree of polymerisation of 2–6 is soluble in CHCl 3. This oligomer shows a photoluminescence quantum efficiency >50% and λ em lies in the blue-green range.
