been studied, often employing p-conjugated compounds with thiol end groups. Experimental results at low temperatures indicate that the three-terminal devices studied so far operate in the weak coupling regime in which the discrete molecular energy-level structure remains essentially intact. Herein we present charge-transport phenomena in threeterminal molecular junctions based on bis(sulfur-end-functionalized) tercyclohexylidene 1. Compound 1 and the monosulfur reference compound 2 are oligo(cyclohexylidenes), which consist of cyclohexane-type rings interconnected bydouble bonds. [15] Their s–p–s orbital topology allows transannular electronic interactions and mediates charge transport through the partlysaturated hy drocarbon framework, as demonstrated bythe occurrence of long-range photoinduced charge separation.
