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 IR and UV-Vis absorption spectra.
