Liquid crystal mixtures with the chiral benzoate dopant

ABSTRACT

The results of studies conducted by means complementary methods: differential scanning calorimetry, transmitted light intensity measurements, polarized optical microscopy and electrooptical methods of two new liquid crystal mixtures are presented. The investigated mixtures consist of achiral thiosobenzoates, 7OS5 and 8OS5, and a chiral addition of benzoate, MHOBCO6. In all mixtures there is a wide low temperature range of the existence of the ferroelectric SmC* phase.
