Porphyrin Assembly on β-Cyclodextrin for Selective Sensing and Detection of a Zinc Ion Based on the Dual Emission Fluorescence Ratio

In the present paper, a new cyclodextrin/porphyrin supramolecular sensitizer for zinc ion has been proposed based on the porphyrin dual fluorescence emission ratio. In aqueous solution, meso-tetraphenylporphyrin shows weak fluorescence, while in the presence of alkylated β-cyclodextrin, it exhibits...
