Abstract

Abstract: In this paper the solubilization and the photophysical properties of HA in micelles (Triton X-100, TDPB, SDS) were investigated. Experimental results proved that HA can be solu-bilized into different kind of micellar aqueous solution, the abilities of solubilization for HA are as showing: Triton X-100 > TDPB > SDSThe concentration of HA in the range of 10^-5-10^-4 mol/L in micelles can be easily prepared. It provided a condition to search for an excited state’s behaviors of HA in aquenous system. The tautomerization of HA in micelles were observed at lower occupancy number and the enconter complex of HA at high occupancy number in ground state was formed in TDPB micelle at λ_max 630nm, corresponding to λ_max 670nm for an excimer of HA in excited state.

Key words: hypocrellin A, micelles, solubilization, photophysical behaviors
