Poly(distyrylbenzene-block-sexi(ethylene oxide)), a highly luminescent processable derivative of PPV.
A block copolymer of distyrylbenzene with sexi(ethylene oxide) spacers displays high solid state photoluminescence efficiency (34%). Single layer light-emitting diodes with calcium or aluminium cathodes exhibit luminances over 2000 cd m-2 and efficiencies of 0.5 cd A-1.
