| 中文摘要 | novel photochromic inorganic-organic multilayers composed of polyoxometalates and poly(ethylenimine) have been prepared by the layer-by-layer (lbl) self-assembly method. the growth process, composition, surface topography, and photochromic properties of the multilayer films were investigated by uv-visible and fourier transform infrared spectroscopy, atomic force microscopy, electrospin resonance (esr), and x-ray photoelectron spectroscopy (xps). irradiated with ultraviolet light, the transparent films changed from colorless to blue. moreover, the blue films showed good reversibility of photochromism, and could recover the colorless state gradually in air, where oxygen plays an important role in the bleaching process. on account of the esr and xps results, parts of w6+ in multilayers were reduced to w5+, which exhibited a characteristic blue; a possible photochromic mechanism can be speculated. this work provides basic guideline for the assembly of multilayers with photochromic properties. |
