TICT Induced Fluorescence Color Change Actualized in an Organogel System

A dimethylaminobenzoate group (TICT probe) was conjugated with a cholesterol group to assess the microenvironmental effect of the gel fibrils by a fluorescence method. It was found that the solvent-dependent dual fluorescence mode characteristic of TICT molecules in the sol phase almost disappears in the gel phase and only the shorter-wavelength fluorescence arising from the coplanar conformation is observed.
