Abstract
The synthesis of unsubstituted meta-para oligo-phenylenevinylene (mp-OPV) w as carried out via metathesis polycondensation (acyclic diene metathesis po lymerisation ADMET) of commercially available divinylbenzene (55% in ethylv inylbenzene). A stable molybdenum carbene complex of the Schrock type serve d as initiator. The obtained mp-OPV, which is an intensively yellow powder, with a degree of polymerisation of 2-6 is soluble in CHCl3. This oligomer shows a photoluminescence quantum efficiency > 50% and lambda(em) lies in t he blue-green range. (C) 1999 Published by Elsevier Science S.A. All rights reserved.
