PREPARATION OF NEW POLY(PHENYLENE VINYLENE) TYPE POLYMERS BY NI-PROMOTED POLYCONDENSATION AND THEIR PHOTOLUMINESCENT PROPERTIES

Poly(p-phenylene vinylene) type polymers having biphenyl-4,4′-diyl units have been prepared by organometallic polycondensation. They are photoluminescent and electrochemically active, and are considered to take a stacked and liquid crystalline structure depending on the substituent.
