ELECTROCHROMIC MATERIAL INCLUDING A VIOLOGEN MOIETY AND A SUBSTITUENT CONNECTED TO ONE SIDE OR BOTH SIDES OF THE VIOLOGEN AND AN ELECTROCHROMIC DEVICE INCLUDING THE SAME

摘要

PURPOSE: An electrochromic material is provided to ensure low absorptivity and high permeability of a soft green wavelength range in about 1 V or to also ensure low absorptivity and high permeability of a dark green wavelength range in about 1.5 V.;CONSTITUTION: An electrochromic material comprises a compound represented by chemical formula 1. An electrochromic device comprises: a first electrode and a second electrode which are faced to each other; the electrochromic material positioned at one of first and second electrodes; an electrolytic layer located between the first and second electrodes. The electrochromic material displays other colors in a different voltage range. The electrochromic material displays green in a first voltage range and red in a second voltage range.;COPYRIGHT KIPO 2012
