Formation of a highly ordered red phase in a MEH-PPV: polystyrene pseudogels

Abstract

In this work, we demonstrate the formation of a "red-phase" poly[2-methoxy, 5-(2'- ethyl-hexoxy)-1,4-phenylene vinylene-PPV] (MEH-PPV) embedded into a host matrix of highly entangled ultra-high molecular weight polystyrene (MEH-PPV/UHMW PS pseudogel) that allows the simple processing of the MEH-PPV solutions. We processed a "red-phase" in the gel, the gel shows that the features what have beed demonstrated in the solution can be observed in the processable gel for optoelectronics applications.
