The application relates to a strongly-polarized molecule of the following general formula: wherein A denotes a group having a polarizability greater than 2 C·m/V; Rand Rare respectively hydrogen, halogen, a hydroxyl group, an amino group, a cyano group, a nitro group, a carboxyl group, a Calkyl group, a Calkoxy group, a halogenated Calkyl group, a halogenated Calkoxy group, a hydroxyl Calkyl group, a hydroxyl Calkoxy group, or a Calkyl amino group; xand xdenote 0 or an integer no less than 1, respectively; and yand ydenote 0 or an integer no less than 1, respectively. The application further relates to a strongly-polarized molecule-graphene molecule heterojunction, and a single molecule field effect transistor comprising a substrate, a gate, a dielectric layer and the strongly-polarized molecule-graphene molecule heterojunction; and the dielectric layer is located between the gate and the strongly-polarized molecule-graphene molecule heterojunction. The single molecule field effect transistor provided by the application can realize highly-efficient gate modulation.
