  The present invention relates to optical articles and optical filtering coatings comprising at least one absorbing dye comprising one of the groups of formulae of formulae (I), (II), (III) and (IV), wherein R represents an aryl or alkyl group, and the groups of formulae (I), (II), (III) and (IV) have at least one carbon atom substituted with a group chosen from -OH, -CN, bromo, -NO2, alkoxy, aryloxy, -COOH, -CHO, -COalkyl, -COaryl, haloalkyl, -SH, -S-alkyl, -S-aryl, -SO2alkyl,-OSO2alkyl, -SO2aryl, -OSO2aryl and sulfonamide, or have at least two carbon atoms substituted with a chloro group.

  (III)和(IV)的基团至少有一个碳原子被选自-OH、-CN、溴、-NO2、烷氧基、芳氧基、-COOH、-CHO、-COalkyl、-COaryl、卤代烷基、-SH、-S-alkyl、-S-aryl、-SO2alkyl、-OSO2alkyl、-SO2aryl、-OSO2aryl 和磺酰胺的基团取代，或至少有两个碳原子被氯基取代。
• Color tuning of electrochromic devices using an organic dye
  申请人：THE UNIVERSITY OF CONNECTICUT

  公开号：US10323178B2

  公开（公告）日：2019-06-18

  Disclosed is a method to color tune an electrochromic device by the use of a standard dye. By following the “subtractive color mixing” theory and selecting the appropriate standard dye to compliment or accentuate the electrochromic material, tuning of the optical and colorimetric properties of the resulting electrochromic device can be achieved. The method can also be used to prepare electrochromic devices that will switch between two neutral colors.

  本发明公开了一种通过使用标准染料对电致变色装置进行颜色调节的方法。根据 "减色混合 "理论，选择适当的标准染料来衬托或突出电致变色材料，就可以实现对电致变色装置的光学和色度特性进行调整。该方法还可用于制备在两种中性色之间切换的电致变色装置。
