A novel blue-light-emitting functional copolymer containing alternating rigid eonjugated PPV and flexible ionic conductivity PEO blocks in the main chain was synthesized by using the Wittig reaction.The copolymer was characterized by FT-IR
1H-NMR
UV-Vis
DSC
GPC
etc.The resuIts show that the copolymer can be soluble in chloroform and tetrahydrofuran
with Tg=50.5℃
Td=20℃
amaximum absorption peak in UV-Vis spectrum at 354nm and an emission peak in the photolumineseent spectrum at 438nm for solution in chloroform and at 475nm for film It is a good blue emitter for fabricating LED or LEC.
