Research Progress on Liquid Crystals of Schiff bases and their Metal Complexes

介绍了席夫碱及其金属配合物液晶的最新研究进展,重点介绍了含α-氰基二苯乙烯、胆甾醇、偶氮苯及手性基团的棒状或弓形的席夫碱液晶,介绍了他们液晶性质以及他们作为聚集发光材料、光响应材料、手性以及铁电材料等的潜在应用。指出:通过灵活的化学分子结构的设计,将赋予席夫碱液晶更加丰富和复杂的液晶自组装结构和性质,将会给席夫碱液晶的发展带来新的突破。

In this paper,the latest research progress of Schiff bases and their metal complex liquid crystals was introduced.The rod-shaped or bent-shaped Schiff base liquid crystals containingα-cyanostilbene,cholesterol,azobenzene and chiral groups are mainly introduced.Their liquid crystal properties and their potential application as aggregation luminescent materials,photoresponsive materials,chiral and ferroelectric materials are introduced.It is pointed out that the design of flexible chemical molecular structure will endow Schiff base liquid crystals more a-bundant and complex liquid crystalline self-assembly structures and properties,which will bring new breakthroughs to the development of Schiff base liquid crystals.
