In recent years bent-core (BC) liquid crystals have begun to mature into a relevant subfield of research. The shape and symmetry of BC molecules offers a wealth of new questions not presented by calamitic liquid crystals, many of which have yet to be addressed. In this work, I use magnetic field induced birefringence, dynamic light scattering, and density measurements to provide evidence of a transition between two optically isotropic phases in two BC liquid crystals, and to show that this transition can be understood in the framework of the theoretically predicted, but previously unobserved...
