The Fluorescence Quenching in the Complex of Crown-ether Substituted Phthalocyanine and Electron Acceptor
Abstract:
Phthalocyanies bearing one crown-ether void can form complex with electron acceptors which contain alkai metal ions. The electron transfer reactions could be accelerated by the formation of the complex and the fluorescence of phthalocyanine was quenched significantly in this system. No fluorescence quenching of phthalocyanines without crown-ether substituted was observed under the same conditions. The steady constants of the complex can be calculated by non-linear least square fit method.
