1B10 有機金属錯体のディスコティック液晶(70) : 新規なbis[1,3-diphenylpropane-1,3-dithionato]nickel(II)系金属錯体液晶の合成とそのdiscotic lamellar液晶性(化学・材料)

抄録

Four long-chain-substituted disk-like molecules tend to show discotic lamellar (D_L) mesophases. However, there have been very few reports on D_L-showing compounds. To date, four kinds of D_L mesophases have been found. In order to further clarify D_L mesophases, we have synthesized two new metal complexes, la and 1b. It was established from microscopic observation and temperature-dependent X-ray diffraction studies that the mesophase of 1b is a D_<L1> mesophase. We discuss differences between the discotic lamellar mesophases and smectic ones.
