摘要：

For the first rime two series of carbosilane liquid crystalline dendrimers of generations 1 - 3 with 8, 16 and 32 terminal ethyl-L-lactate-containing mesogenic groups, respectively, have been synthesized. Structures and purity of all new compounds were confirmed by H-1 NMR spectroscopy and GPC analysis. All the LC dendrimers synthesized exhibit a chiral smectic C mesophase in a broad temperature range. The spontaneous polarization was measured. It has been found that spontaneous polarization is reduced with increase of generation number.
