Solvent affects fluorescence
WebThe main fluorescence emission band of FP1 at 480 nm (in hexane) is shifted to longer wavelengths with increasing polarities of solvents. Linear Lippert's plot and linear correlation between bands maxima and Camlet-Taft parameter, α, of the protic solvents indicated efficient intramolecular charge transfer and noticeable H-bonding. WebThe effect of contact time, solvent system, concentration and substituents was also studied during investigation of fluorescence properties of these derivatives. ...
