A new columnar cholesterogen based on the octasubstituted phthalocyanine(PcH2), (+)-2,3,9,10,16,17,23,24-octakis[4-(dodecyloxy)-2-oxa-pentyl ]-phthalocyanine (1), is described. The chiral PcH2 1 exhibited classical cholesteric textures in which the transition of platelet to fan-shaped texture was observed (K\xrightarrow23°CM\xrightarrow158°CI). This is the first instance of columnar cholesterogen observed
基于八取代的酞菁(PcH2), (+)-2,3,9,10,16,17,23,24-octakis[4-(dodecyloxy)-2-oxa-pentyl]-phthalocyanine ( 1), 描述。手性 PcH2 1 表现出经典的胆甾型结构,其中观察到血小板向扇形结构的转变(K\xrightarrow23°CM\xrightarrow158°CI)。这是用盘状液晶系统观察到的柱状胆固醇的第一个实例。
