General description
Poly{[2-[2′,5′-bis(2″-ethylhexyloxy)phenyl]-1,4-phenylenevinylene]-co-[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylenevinylene]} ((BEHP-PPV)-co-(MEH-PPV)) is a poly(phenylenevinylene) derivate that is highly resistant to photo degradation. It has a high solubility in solvents like chloroform, THF and xylene.
Application
((BEHP-PPV)-co-(MEH-PPV)) is a conjugating polymer that can be used as an active layer in the fabrication of a variety of organic semiconducting devices such as light emitting diodes (LEDs), photovoltaic cells, and photonic crystal lasers.
Light emitting polymer.
Features and Benefits
More stable to photooxidation than other substituted PPV derivatives.
