Abstract:

In this paper, the effects of the concentration of Hypocrellin A, solvents, acid, bases, dispersing agents and temperatures on the fluorescence spectra of Hypocrellin A have been studied in detail. It was proved that the action of solvents on Hypocrellin A is closely related to the characteristics of solvents.The proton transfer of the excited Hypocrellin A is weakened at low temperature. In order to compare with Hypocrellin A, Hypocrellin B has also been studied parallelly, consistent conclusions were reached. In addition, it was found out that Hypocrellin A and B can be acted as a new kind of fluorescence probes to study the multi-environment of micellar and biological macromolecular systems.
