英文摘要	Three aromatic (p-carboxyl phenyl) esters, 4-(benzoyloxy) benzoic acid, 4-(4'-methylbenzoyloxy) benzoic acid, and 4-(4'-chlorobenzoyloxy) benzoic acid, were synthesized and they showed nematic monotropic or thermotropic behavior. The mesogen-linked cellulose acetates were first prepared by the reaction of aromatic (p-carboxyl phenyl) esters with cellulose acetate through esterification in the presence of N,N-dicyclohexylcarbodiimide (DCC) and 4-dimethylaminopyridine (DMAP). Their degrees of mesogenic unit substitution (DS-meso were between 0.27 and 0.41. It was found that they can form cholesteric lyotropic phases in dichloroacetic acid and their critical concentration was about 25 wt %. (C) 2004 Wiley Periodicals, Inc.
