摘要：

The preparation and characterization of sol-gel composites fur fluorescent detection of solvents (using dansyl-labelled beta-cyclodextrin) and Al3+ ions (using Morin), and for colourimetric detection of Cu2+ (using Eriochrome Cyanine R) is described. The active roles played by both the entrapped reagent and the sol-gel matrix in the sensing processes are discussed.
