Title: Manipulation of multiple-responsive fluorescent supramolecular materials based on the inclusion complexation of cyclodextrins with Tyloxapol
Abstract: A fluorescent supramolecular hydrogel was prepared by alpha-cyclodextrin and Tyloxapol, which can be considered as an oligomer of the surfactant polyoxyethylene tert-octylphenyl ether (Triton TX-100) with a polymerization degree below 7. For comparison, Tyloxapol and TX-100 were selected to form hydrogels with alpha-CD get more information about the interaction between different types of and cyclodextrin. These hydrogels have been thoroughly using various techniques including phase behavior transmission electron microscopy (TEM), field emission electron microscopy (FE-SEM), fluorescence spectra, microscopy observations, Fourier transform infrared (FT-IR) 1H NMR, 2D H-1-H-1 ROESY NMR, small-angle X-ray scattering X-ray diffraction (XRD) and rheological measurements. The of alpha-CD/Tyloxapol are responsive to external stimuli temperature, pH and guest molecules, and present quenching fluorescence emission properties. The reason this phenomenon may be that Tyloxapol molecules come into the cavity alpha-CD and form the inclusion complexes. Due to the high electron of the narrow cavity of alpha-CD, it induces the shift of the on the benzene ring which can weaken the pi-pi interaction and to the fluorescence quenching. Moreover, the hydrogel formed by is highly responsive to the formaldehyde (HCHO). The of a small amount of HCHO can induce a gel-to-sol transition. once the gel transforms into solution, it becomes This makes the alpha-CD/Tyloxapol hydrogel a promising for HCHO detection and removal in home furnishings to reduce indoor environmental pollutants.
