摘要
Abstract
4-Alkoxy-biphenyl-4′-carboxy-lates(2-n) was synthesized by introducing a benzyl ring on the side of alkoxy chain of chromen-2-one-6-yl 4-alkoxy benzoates(1-n). The liquid crystalline and gelation of compound 2-n were determined. Comparing with compound 1-n, compound 2-n exhibits enantiotropic nematic phase and can form gels with various organic solvents. The critical gel concentrations in various solvents were determined and the three-dimensional network structure consisting of xerogel fibrils was observed with a scanning electron microscope. Conclusively, intermolecular interactions around lactone moiety having a broad shape and a large dipole moment play important roles in enhancing the broad gelling ability.关键词
