  • Anodic electrochromic materials having a solublizing moiety
    Patent number: 6262832
    Abstract: Anodic electrochromic materials for use in an electrochromic device comprising a first moiety, wherein the first moiety comprises a metallocene or a substituted metallocene, and a second moiety, wherein the second moiety comprises at least one constituent which serves to increase the solubility of the first moiety in an associated solvent relative to solubility of the first moiety without the second moiety.

  • Near infrared-absorbing electrochromic compounds and devices comprising same
    Patent number: 6193912
    Abstract: Electrochromic compounds capable of reversibly attenuating the transmittance of the near infrared portion of the electromagnetic spectrum are provided. These compounds exhibit an energy difference between the singly occupied molecular orbital (SOMO) energy and the highest doubly occupied molecular orbital (HDOMO) energy (ESOMO−EHDOMO) of less than about 3.6 eV. In addition, these compounds have a transition moment of the configuration made up of the HDOMO and SOMO that is “long axis polarized”.
