The photophysics and structural transition dynamics of a bio-active flavin lumichrome (LM) entrapped in two sugars based neutral surfactants are reported. Sugar-based surfactants, which were used for research purpose are potential environmentally friendly, green alternative amphiphilic surface active substance compared to other kinds of common surfactants. Here, two alkyl glucoside surfactants n-octyl-β-D-glucopyranoside (OBG) and n-octyl-β-D-thioglucopyranoside (OBTG) were used. This work was carried out by using steady-state absorption and fluorescence emission spectroscopy along with time-resolved fluorescence emission techniques. Photophysics of LM was modulated several folds in these two sugar-based neutral micelles. LM exhibits excitation and emission wavelength dependent fluorescence properties in these two sugars based neutral micelles. LM confined in the micellar environments exhibited structural transition dynamism, i.e. different kinds of conformers are equilibrated. Herein, different conformers of LM are identified and explained with the help of spectroscopic methods. From the fluorescence anisotropy measurement, the rotational relaxation time of LM in OBG micelle was more compared to that in OBTG micelle, which indicates that the LM mol. faced much more constrained environment in OBG micellar media.
