Molecular conductance of dendritic wires

Steady-state rates of electron transfer through molecular bridges are used to calculate the conductance through molecular wires. The study focuses on the topology of the molecular bridge and the implications for the conductance through particular structures. Here we demonstrate an enhanced steady-state flux of electrons through dendritic wires. A calculation of the steady-state rates illustrates that branched topologies, and in particular dendritic structures, can show larger conductance than the linear chain counterparts. The position and the topology of the side branches are shown to be crucial in determining these transport properties.
