Theoretical models of directional proton molecular transport
The important topic of proton transport through molecular wires is usually associated with the Grotthuss mechanism. In this paper we propose an alternative conductor based on chains of lone pairs. B3LYP/6–31+G** and PW91 DFT calculations on model compounds (1,2,3,4-tetrasubstituted benzenes) show that these compounds could play the role of proton conductors.
