Abstract:
A photochromic dithienylethene‐bridged bis(permethyl‐ β ‐cyclodextrin)s was successfully synthesized through an amide condensation reaction, and its photochromic properties were also investigated by 1 H NMR spectra and UV/vis spectroscopy. Moreover, taking advantage of the strong interaction between permethyl‐ β ‐cyclodextrin and water soluble porphyrins, a supramolecular nanowire was then successfully constructed and characterized by UV/vis spectroscopy, atomic force microscopy (AFM), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). Significantly, the fluorescence resonance energy transfer (FRET) process from the porphyrin to the dithienylethene core can be modulated by alternate irradiation with ultraviolet and visible light and, thus, light‐controlled quenching and recovery of fluorescence of porphyrins was realized.
