Abstract
Oligo-and poly-mp-phenylene vinylenes were synthesized via metathesis and Heck coupling chemistry using (a) unsubstituted mand p-divinylbenzenes, (b) unsubstituted mand p-divinylbenzenes copolymerised with norbornene diacetate and (c) unsubstituted pdivinylbenzene and 4-alkoxy-1,3-dibromobenzene (alkoxy = pentyloxy and decyloxy). For (a) it could be observed that there is a shift to the blue in the photoluminescence if the concentration of incorporated m-units in the oligomers is increased, for (b) that the quantum efficiency is > 50% and for (c) that the substituents have little influence on the photoluminescence.
