possessing even number of carbon atoms at the terminal alkanoyloxy chain (Cn-1H2n-1COO-, n = 4,6,8,10,12,14) was synthesized. n-Butanoyloxy was found non-mesogenic, whilst n-hexanoyloxy to n-tetradecanoyloxy exhibited enantiotropic smectic A phase with fan-shaped texture. It was found that the length of terminal alkanoyloxy chain influenced the mesomorphic properties.
一系列偶氮甲酸酯,在末端烷酰氧基链上具有偶数碳原子的3-羟基-4-[((4-碘苯基)亚氨基]甲基}苯基}链烷酸酯(C n-1 H 2n-1 COO-,n = 4,6,8,10,12,14)被合成。Ñ -Butanoyloxy发现非介晶,同时Ñ -hexanoyloxy到Ñ -tetradecanoyloxy展出互变近晶A与扇形纹理相。发现末端烷酰氧基链的长度影响介晶性质。
