Electrochromic compounds capably of reversibly attenuating the transmittance of the near infrared portion of the electromagnetic spectrum are provided. Theses compounds exhibit an energy difference between the singly occupied molecular orbital (SOMO) energy and the highest doubly occupied molecular orbital (HDOMO) energy (E SOMO-E HDOMO) 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".
L'invention concerne des composés électrochromiques capables d'atténuer de manière réversible la transmittance de la partie du proche infrarouge d'un spectre électromagnétique. La différence (ESOMO-EHDOMO) entre l'énergie SOMO (single occupied molecular orbital) et l'énergie HDOMO (highest doubly occupied molecular orbital) de ces composés est inférieure à 3,6 eV environ, le moment de transition de la structure composée par ces énergies HDOMO et SOMO étant par ailleurs "polarisé le long de l'axe longitudinal".
