摘要

Novel fluorescent vesicles based on inclusion complexes of beta-cyclodextrins (beta-CD) with Tyloxapol were constructed. For comparison, alpha-cyclodextrins (alpha-CD) were also selected to form inclusion complexes with Tyloxapol. The vesicles formed by beta-CD/Tyloxapol were characterized thoroughly using various techniques including phase behavior observation, transmission electron microscopy (TEM), freeze fracture transmission electron microscopy (FF-TEM), field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM), 2D H-1-H-1 ROESY NMR, fluorescence spectra, Fourier transform infrared (FT-IR) spectroscopy, and X-ray diffraction (XRD). The results of TEM, SEM, FF-TEM, AFM indicated the formation of vesicles of beta-CD/Tyloxapol; they presented aggregation-induced emission enhancement properties because the alkyl chain of Tyloxapol molecules enters the cavity of beta-CD and forms inclusion complexes, while alpha-CD/Tyloxapol showed aggregation-induced quenching fluorescence emission properties owing to the interaction between PEO chain of Tyloxapol molecules and alpha-CD. Moreover, the vesicles of beta-CD/Tyloxapol were responsive to external stimuli and their fluorescent intensities were changed by various environmental conditions such as urea, phenylalanine, alpha-amylase and NaOH. These properties made our vesicle a promising candidate as novel, smart, stimuli-responsive, fluorescent vesicular sensors.
