A Crystalline Molecular Gyrotop with a Biphenylene Dirotor and its Temperature Dependent Birefringence

Abstract

Biphenyl contains a direct bond between two phenyl functional groups, and the dihedral angle between the two phenyl groups has been discussed in terms of electronic and steric stabilization. Facile rotation about the C–C bond between the two phenyl components is expected to occur at high temperature. Here, we report observations of the rotational dynamics of. The structure and rotational dynamics of the rotor exhibit a remarkable temperature dependence. In accordance with the amplification of the angular displacement of the biphenylene inside a crystal with increasing temperature, the birefringence of the single crystal decreased.
