Four novel triphenylene-Bodipy dyads were synthesized in yields of 32–38% and characterized by MS, NMR, elemental analysis. They exhibit good columnar liquid crystal behaviors at room temperature. The alkyl substitution on the Bodipy unit does not cause the disruption of the mesophase. They possess excellent fluorescence properties with high quantum yields in solution and the weak fluorescence in film. The alkyl substitutions on the Bodipy unit increase the fluorescence intensity and the introduction of triphenylene units reduce the aggregation-caused quenching of orderly stacking of Bodipy units.
Ion complexation-induced mesomorphic conversion between two columnar phases of novel symmetrical triads of triphenylene-calix[4]arene-triphenylenes

Two novel symmetrical triads of triphenylene-calix[4]arene-triphenylenes 6a and 6b bridged by hydrazone spacers were synthesized in high yields. They possessed interesting ion complexation-induced mesomorphic conversion between two columnar phases. The neat compounds 6a and 6b showed mesophase with calixarene's bowlic column as cores. The Ag+-complexes of 6a and 6b exhibited mesophase with triphenylene column as cores.
