General description

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.

Application

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.

Features and Benefits

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.
