By applying first-principles method based on density functional theory combined with nonequilibrium Green’s function, we investigate the effect of torsion angle on the electronic transport properties in dipyrimidinyl–diphenyl co-oligomer molecular device with tailoring graphene nanoribbon electrodes. The results show that the torsion angle plays an important role on the electronic transport properties of the molecular device. When the torsion angle rotates from 0[Formula: see text] to 90[Formula: see text], the molecular devices exhibit very different current–voltage characteristics which can realize the on and off states of the molecular switch.

Terpineol leads to effective exfoliation and excitonic enhancement in solution dispersions of MoS2 and WS2, which also yields enhancement in electronic transport properties. Such dispersions are amenable to high-performance electronic and opto-electronic devices using manufacturable routes.
