Abstract

We review the principles of optical sensor based on the use of the sol-gel technique, in particular their fabrication. We also report on potential applications of the recognition phases prepared by encapsulation of fluorescent chemosensors which have been designed by means of a supramolecular approach: two anthryl groups linked to diaminodiethero group. Occurrence of the metal ion-receptor interaction is signaled through the enhancement of anthryl fluorescence. The enhancement takes place when the receptor is able to promote a photoinduced electron transfer mechanism. Cu(II) ions can be distinguished form other transition metal ions in aqueous solution by the recognition phase.
