摘要: FDAPT (2-formyl-5-(4'-N,N-dimethylaminophenyl)thiophene) is an efficient environment-sensitive fluorescent probe, which senses the alteration of its microenvironment with six different parameters, namely, emission intensity, wavelength, fluorescence anisotropy, and corresponding three time-dependent parameters lifetime, time-resolved spectrum, anisotropy decay. In present work, nature saccharide-induced dehydration a F127 polymeric micelle investigated in detail emission. Using multiparametric approach, it observed that saccharide molecules not only decrease critical micellization temperature solution but also strongly alter physical properties inside micellar structures. The local polarity fluidity significantly as compared to normal micelle. probe solvation dynamics study reveals water content core well corona domain diminishes More precisely, occurs more region than region. Also, alters relative size regions. extent varies molecules. It found efficiency order trisaccharide (raffinose) > disaccharide (sucrose) monosaccharide (glucose fructose).
