摘要合成并表征了端基为氰酸酯基的席夫碱液晶。随后化合物M的环三聚将三个氰酸酯末端聚在一起形成s-三嗪环，并产生具有三重对称性的大分子T。T的中间相转变温度高于M。S-三辛环适当地用作介晶三聚体T的中心核。
Abstract Liquid crystalline Schiff-base (M) with a cyanate terminal group was prepared and characterized. Subsequent cyclotrimerization of compound M brings together three cyanate terminals to form a s-triazine ring and produces a large molecule, T, with three-fold symmetry. The mesophase transition temperatures of T are higher than M. The s-trisine ring serves appropriately as central core of the mesogenic trimer, T.
