Mesomorphic properties of three-benzene-ring containing bent-core 1,3-phenylene-bis4-(alkylcarboyioxyl)benzylidenearnine

摘要：

A homologous series of three-benzene-ring containing bent-cores compounds 1,3-phenylene-bis4-(alkylcarboyloxyl)benzylideneamine were synthesized. In these molecules the terminal ester chains CH3(CH2)n-2COO-, where n was the number of carbon atoms in the terminal chains, were linked to the central three-benzene-ring containing bent-core. As n changed from 1-12,the melting temperatures and clearing points were in the high temperature ranges of 136-206℃. As n changed in the range of 14-19, the melting temperatures and clearing points were dramatically dropped in a low temperature ranges 60-82℃.
