Study on the Interaction of Coumarin with [beeta] – cyclodextrin by Absorption and Fluorescence Spectroscopy

The ability of β-cyclodextrin (β-CD), to break the aggregate of the coumarin and to form 1:1 inclusion complexes has been studied by absorption and fluorescence spectroscopy. Experimental conditions including concentrations of β-cyclodextrin were investigated for the inclusion formation in detail. The formation constants are calculated by using steady – state fluorimetry. The infrared spectroscopy and scanning electron microscopy were studied to conform the inclusion complex.
