An investigation of the electronic properties of coumaries

Coumarin derivatives represent one of the most important chemical classes of organic fluorescent materials. Ground and excited state formation constants of coumarin with hydroxyl propyl β-cyclodextrin (HβCD) were calculated by using absorption and fluorescence spectroscopy. The free energy changes have also been calculated from the formation constants. The interactions of coumarics with HβCD was studied by FTIR and SEM analysis also. © 2010 IJRSR. All rights reserved.
