Abstract
A reconfigurable polar molecule includes a symmetric nonpolar molecule portion having an elongated shape defined by a longitudinal axis and lateral axis, the longitudinal axis being longer than the lateral axis; a positive ionically charged group at a first end and a negative ionically charged group at a second end of the longitudinal axis, the positive and negative ionically charged groups forming a permanent dipole; a first bridging group and a second bridging group on opposing ends of the lateral axis, the first and second bridging groups being linear nonpolar groups; and a first support portion bonded to the first bridging group, and a second support portion bonded to the second bridging group, the first bridging group and the second bridging group being nonpolar and having structures that enable free rotation of the symmetric nonpolar molecule portion through the first bridging group and the second bridging group.
