Unusual Properties of Amphiflavins in a Binary Solvent

Abstract
The interaction of amphiflavins in organic solvents and a binary (ethanol/water) solvent has been studied. The absorption spectra, steady state and phase sensitive fluorescence spectra, lifetimes, anisotropy and quantum yield of fluorescence have been measured. In a binary solvent the interaction between the amphiflavin molecules and the microenvironment of different polarity leads to the selforganization of amphiflavins. As a result organized structures of amphiflavin molecules appear.
