Polydiacetylenes (PDAs) have attracted much attention in recent years due to their potential electronic, biological, and optical applications. With backbones composed of sp<sup>2</sup> and sp hybridized carbons, these conjugated organic polymers can serve as precursors to graphene, sensor material, and as components in various electronic materials. The electronic properties of polydiacetylenes can be modified by attaching different end-groups, particularly those with electron-withdrawing or electron-donating capabilities. End-groups that contain sulfur have rarely been incorporated into PDAs, therefore this research focuses on the synthesis of diynes with thiocyanate- and thiophene- functionalities. The synthesis of 1,4-di(thiophen-2-yl)buta-1,3-diyne was achieved using previously reported methods; however 1,4-dithiocyanatobuta-1,3-diyne has not been reported in the literature. Polymerization experiments with both diynes are currently in progress.
