Abstract
We have investigated the optical properties of a series of poly(p-phenylene
vinylene) (PPV) copolymers. Three-wide bandgap PPV copolymers were synthes
ized and characterized. The new PPV copolymers showed a large blue shift in
both absorption and emission that their average bandgap is over 3.1 eV. A
significant solvatochromic effect was observed in the photoluminescence (PL
) spectra of copolymers. The dimethoxy-substituted copolymer showed the hig
hest quantum efficiency and processability among three copolymers. (C) 2000
