Abstract :
A new series of porphyrin-containing PPV-copolymers have been synthesised. The porphyrin units are attached as a side group on the main chain, in an effort to attempt to control aggregation and consequent fluorescence quenching. Emission is red-shifted from that expected in dialkoxy-PPVs owing to an efficient exciton transfer to the fluorescent porphyrin unit, leading to a more useful red colour for RGB displays. The effects of the porphyrin concentration on the PL efficiencies will be reported.
