We will report our recent work on the synthesis of new molecules which anchor in single-molecule junctions, and the characterization of their conductance properties using break junction techniques. We will particularly focus on two studies: (i) OPE-type systems with heteroaromatic cores, where our study establishes that both heteroaromaticity and quantum interference in the molecular core units play important and inter-related roles in determining the conductance of single molecule junctions. (ii) OPE derivatives with a phenothiazine core unit that can readily form a cation radical, leading to a dramatic radical enhanced conductance. The experimental results of these two studies are supported by theoretical calculations.
