Abstract

We report a combined experimental and theoretical investigation of the length dependence and anchor group dependence of the electrical conductance of a series of oligoyne molecular wires in single-molecule junctions with gold contacts. Experimentally, we focus on the synthesis and properties of diaryloligoynes with n= 1, 2, and 4 triple bonds and the anchor dihydrobenzo [b] thiophene (BT). For comparison, we also explored the aurophilic ...
