Abstract

We report influence of magnetic flux on the quantum transport in a aromatic $\pi$ conjugate system made up of two phenyl rings separated by an insulator group. In the presence of a transverse magnetic field the transmission, the dipole moment and the energy of the system gives oscillatory behaviour with flux $\phi$, threaded by the molecular ring showing flux quantum periodicity. This aspect may be utilized in designing nano-scale electronic devices.
