Soluble poly(2,5-di-t-butyldimethylsilyloxy-1,4-phenylenevinylene) was prepared via a Stille coupling reaction between 2,5-diiodo-1,4-bis-(t-butyldimethylsilyloxy)benzene and E-1,2-bis(tri-n-butylstannyl)ethylene in the presence of tetrakis-(triphenylphosphine)palladium(0) as the catalyst. The characterization of this material by H-1- and C-13- NMR, UV-Vis., and IR spectroscopies is described. The molecular weights, determined by GPC analysis and referred to standard polystyrene, were M-n = 2027 and M-w = 2621. Photoluminescence measurements were performed in solution and on thin films of pure material or of a blend with polystyrene.

Abstract
Soluble poly(2,5-di-t-butyldimethylsilyloxy-1,4-phenylenevinylene) was prepared via a Stille coupling reaction between 2,5-diiodo-1,4-bis-(t-butyldimethylsilyloxy)benzene and E-1,2-bis(tri-n-butylstannyl)ethylene in the presence of tetrakis-(triphenylphosphine)palladium(0) as the catalyst. The characterization of this material by H-1- and C-13- NMR, UV-Vis., and IR spectroscopies is described. The molecular weights, determined by GPC analysis and referred to standard polystyrene, were M-n = 2027 and M-w = 2621. Photoluminescence measurements were performed in solution and on thin films of pure material or of a blend with polystyrene.File in questo prodotto:
