Synthesis and fluorescence properties of a novel supramolecular complex containing [60]fullerene moiety

A new crown ether styryl dye containing [60]Fullerene moiety has been synth esized, and characterized by FT-IR, NMR and Mass spectra. Fluorescence spec tra of the compound have also been studied. The results indicate a strong h ypsochromic shift from 548 nm to 526 nm is observed on cation complexation, and the intensity of peaks at 504 nm, 548 nm and 590 nm decrease as the me tal cation concentration is increased at 77K.
