Abstract

Nano conjugated thienylethenyl and thienylethynyl compounds with controlled structure and dimensions have been efficiently prepared, by heterocoupling reaction between 1, 4- (thienylethynyl) phenylacetylene (or thienylethenyl) phenylacetylene and 2-or 2, 5- dihalothiophene. Conjugated 1, 4-di (2-thienylethynylphenyl)-(or 2-thienylethenylphenyl)-1, 3-butadiyne were obtained by the homocoupling of the terminal acetylenes in excellent ...
