摘　　要：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 4×10 4g/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.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 x 10(4) 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.
