Abstract:
1. An electrochromic mirror in which an ion conductive layer is arranged between a transparent electrically conductive substrate and a reflective electrically conductive substrate; wherein the ion conductive layer contains an organic compound having a structure exhibiting a cathodic electrochromic property and a structure exhibiting an anodic electrochromic property, and wherein the organic compound comprises a metallocene-bipyridine derivative represented by one of formulas (4) to (7): wherein A − and B − may be the same or different and are each independently a pair-ion selected from the group consisting of a halogen anion, ClO 4 − , BF 4 − PF 6 − , CHCOO − , and CH 3 (C 6 H 4 )SO 3 ; Me is selected from the group consisting of Cr, Co, Fe, Mg, Ni, Os, Ru, V, X—Hf—Y, X—Mo—Y, X—Nb—Y, X—Ti—Y, X—V—Y and X—Zr—Y, wherein X and Y may be the same or different and are each independently selected from the group consisting of hydrogen, a halogen, and an alkyl group having 1 to 12 carbon atoms; m is an integer 0≦m≦4; n is an integer 0≦n≦4; R R R and wherein spacers are dispersed in the ion conductive layer and a difference in refraction index between the spacers and the ion conductive layer is ±0.03 or less.
