Spontaneous Colorimetric Sensing of the Positional Isomers of Dihydroxynaphthalene in a 1D Organogel Matrix

摘要

The recent upsurge of interest in functional and stimuli-responsive organogels has unraveled new and exciting properties of molecules hitherto unknown in solution and the solid state.Hydrogen-bonding interactions between amide,urea,and sugar groups as well as the van der Waals interac- tions between cholesteryl groups have chiefly been utilized so far in the construction of one-dimensional (1D) archilectures suitable for gelation.
