Abstract

Abstract In this paper, we report the synthesis and opto-electronic properties of differentially substituted 1, 4-diethynyl-and 1, 1, 4, 4-tetraethynylbuta-1, 2, 3-trienes. These novel chromophores greatly extend the series of building modules for oxidative coupling, which includes 1, 2-diethynyl-and 1, 1, 2, 2-tetraethynylethenes and 1, 3-diethynylallenes (Fig. 1). A general synthesis of 1, 1, 4, 4-tetraethynylbutatrienes, which tolerates a significant ...
