Abstract
The three secondary nitrogens in a heteroditopic cryptand are derivatized with anthroyl groups to have a cryptand based system in the '(fluorophore)3-spacer-receptor' format. This supramolecular system shows enhancement of fluorescence in presence of metal ions like Cu(II), Co(II), Zn(II). The quantum yields of fluorescence enhancement as well as the photophysical behavior of this system has been compared with those of a trianthryl cryptand where the spacer is a -CH2 group. Such studies provide important clues in the development of photodriven molecular devices and sensors and also understanding of the PET process.
