New symmetrically substituted 1,3,5-triazines as host compounds for channel-type inclusion formation

A new synthetic procedure for the production of symmetrically substituted 1,3,5-triazines by cyclization from aromatic nitriles in the molten state with zinc chloride as a catalyst has been developed and applied for a number of aromatic and fluoro aromatic nitriles. The new triazine 8 [2,4,6-tris(40-bromobiphenylyl)-1,3,5-triazine] is shown to form channel-type inclusion compounds with several aromatic solvents, featuring two different channels in the same crystal.
