Abstract	本发明涉及一种电致变色器件及其应用，所述电致变色器件中含有式I所示的电致变色材料，式I化合物是对紫精化合物的发色团的共轭长度进行调制，在两个吡啶基团间引入噻吩，以延长发色团的共轭长度，调控发色团的氧化还原电势，从而丰富发色团在不同电压作用下的颜色变化，同时引入C1～C7的烷基以及碘离子，调控化合物的变色性能，该化合物用于电致变色器件时，器件能对红外光区的光线有吸收，得到一种对可见和近红外双光区敏感的电致变色器件，并拥有高透过率差值，以及良好的稳定性和循环寿命。该器件可应用于智能窗，可以既遮光又隔热。
Other Abstract	The invention relates to an electrochromic device and an application thereof. The electrochromic device contains an electrochromic material represented by a formula I. A compound represented by the formula I modulate the conjugate length of chromophores of a viologen compound; thiophene is introduced between two pyridine groups so as to prolong the conjugate length of the chromophores, and the redox potential of the chromophores is regulated, so that color change of the chromophores under action of different voltages is enriched; at the same time, C1-C7 alkyl groups and iodine ions are introduced to regulate color change performance of the compound. When the compound is used in the electrochromic device, the device can absorb light in an infrared light region, and the electrochromic devicesensitive to visible-near infrared double light regions is obtained. The electrochromic device has high transmittance difference, good stability and good cycle life, and can be applied to intelligentwindows for both light shielding and heat insulation.
