We develop a model for transport through benzene-based single molecules with an NO2 side-group, which incorporates bond bending between the NO2 and the adjacent benzene ring and successfully reproduces the experimentally observed strong negative differential resistance. Transport through the molecule is assumed to be incoherent and is treated using photon assisted tunnelling.
