The beauty of molecules as electrical components comes not simply from their small size but from the immense diversity of their properties. The subtle influences that can be incorporated with chemical functionality promise control of electrical characteristics. Today, however, the correlation between chemical structure and electrical behaviour is not fully understood. In part, this difficulty arrises as there are factors beyond molecular properties which can influence measured electronic transport. Consequently, it is important to be able to quantify what contribution comes from molecular properties alone. Here, we extend previous work examining the effect on conductance that can be expected from geometry and chemical functionality to include symmetry and chirality.
