Abstract

We have studied the phase transition from the isotropic to B4 phase in a mixture of bent- and rod-shaped molecules. Highly sensitive DSC showed many heat-capacity anomaly peaks upon cooling, strongly suggesting the discrete and sequential growth of helical nanofilaments or their assemblies. Such growth process of the B4 phase was confirmed by IRand UV-Vis absorption spectra.
