Abstract
Using thienyl stannane and palladium-catalyzed (Stille coupling), 1,4-di(5’-carbaldehyde-thiophen-2’-yl)-2,5-dioctyloxy-benzene was synthesized by four steps, the structure was determined by NMR, IR and elemental analysis. The UV-vis absorption and photoluminescence (PL) properties were measured. The absorption bands correspond to π-π transition with the peak at 413 nm in chloroform solution, the compound exhibited an emissive peak at 477 nm and 504 nm in chloroform solution and solid state respectively.
