Descrição geral

Poly[(p-phenylenevinylene)-alt-(2-methoxy-5-(2-ethylhexyloxy)-p-phenylenevinylene)] (p-PMEH-PPV) is a conducting polymer that can be used as an active material in the development of optoelectronic devices. It forms a conjugated-nonconjugated multiblock copolymer which can be used as an electroluminescent polymeric material. It can be potentially operated at low voltages with quick responsive and defined displays.

Aplicação

p-PMEH-PPV can be used as a blue EL polymer for the fabrication of semiconductor devices such as organic light emitting diodes (OLEDs), thin film transistors (TFTs), photovoltaic cells and chemical sensors.

Características e benefícios

Light emitting semiconjugated alternating copolymer.
Light emission blue shifted relative to that for MEH-PPV by introduction of unsubstituted phenylene units with para linkage in the polymer main chain, shortening the effective conjugation length of the polymer.
