Abstract
For the first time a series of carbosilane ferroelectric liquid crystalline dendrimers of generations 1 – 3 with 8, 16 and 32 terminal ethyl-L-lactate-containing mesogenic groups, respectively, has been synthesised. Structures and purity of all new compounds were confirmed by 1H NMR spectroscopy and GPC analysis. All LC dendrimers synthesised exhibit only a chiral smectic C mesophase in a broad temperature range. The highest spontaneous polarization is about 140 nC/cm2 for the LC dendrimer of the first generation and is reduced with increase of generation number.
