摘要

Abstract

Poly(2-methoxy-5-(2′-ethylhexyloxy)-p-phenylenevinylene) (MEH-PPV) has been prepared by a liquid／solid two-phase reaction．The liquid phase is tetrahydrofuran containing 1

4-bis(chloromethyl)-2-methoxyl-5-(2′-ethylhexyloxy) benzene as the monomer and a certain amount of tetrabutylammonium bromide (TBAB) as phase transfer catalyst (PTC)．The solid phase is potassium hydroxide particles with diameters smaller than 0.5 mm．Gelation was found in the polymerization processes．As a result

MEH-PPV is partly soluble because of its large molar mass．Soluble MEH-PPV was obtained by using bromomethylbenzene as retardant regent．The molar mass of soluble MEH-PPV was measured to be 6.4×lO4 g／mol．The Structure of polymer was identified by IR

Raman

UV／vis and PL spectra．A thin compact film of MEH-PPV can be formed by spin-coating and it emit a yellow light．
