Synthesis,Characterization and Photochromism of Inorganic-Organic Hybrid Complexes
摘要
Abstract
Two novel crystalline inorganic-organic hybrid complexes La2K(PMo12O40)(EDTA)4 (1), Ni(PW12 O40 )(EDTA)2 (2)have been successfully synthesized by solution method.The compositions, structure characteristics and photochromic properties of complexes have been systematically researched by infrared spectroscopy (IR),thermogravimetric-differential thermal analysis (TG-DTA),cyclic volta-mmetry (CV ),fluorescent spectrum (FL ),ultraviolet-visible diffuse reflectance spectrum (UV-Vis DRS)energy dispersive spectrometer (EDS)and X-ray power diffraction (XRD).The two hybrid comple-xes display excellent photochromism:under the ultraviolet light irradiation,the color of hybrid complex 1 quickly shifts from yellow to atrovirens,and complex 2 from blue-green to black-gray.Kept in dark at room temperature,the color-changing hybrid complex 1 is stable,showing irreversible photochromism;while complex 2 returns to its original color j ust for 4 h in dark place.The reverse reaction of complex 2 can be accelerated by increase in temperature.Without O2 the reverse reaction of complex 2 will not hap-pened,but in the existence of O2 ,complex 2 exhibits excellent reversible photochromism.It can be con-cluded that the two complexes are all potential optical materials for their fast-responsiveness to light.关键词
