Abstract

A new light-emitting poly(p-phenylenevinylene) (PPV) derivative containing a polyhedral oligomeric silsequioxane (POSS-PPV) and its MEH-PPV copolymers, [Poly(POSSPV-co-MEHPV)]s, have been synthesized through the Gilch polymerization, and their light-emitting properties were investigated. The synthesized polymers were characterized by NMR, GPC, thermogravimetric and elemental analysis. The POSS-PPV and copolymers showed almost the same optical properties as the MEH-PPV, regardless of copolymer composition. The POSS-PPV and MEHPPV all showed their peak absorption at 505 and 496nm, and PL emission maxima at 578 and 581nm. POSSPPV showed higher PL quantum efficiency than the MEH-PPV. Synthesis, characterization and electroluminescent properties of the polymers will be presented.
