Ion complexation-induced mesomorphic conversion between two columnar phases of novel symmetrical triads of triphenylene-calix[4]arene-triphenylenes
摘要:
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. (C) 2012 Elsevier Ltd. All rights reserved.
