摘要：

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, ir; 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.
