Electrochromic material and electrochromic device including the same

An electrochromic material comprising:

• a metal-organic framework comprising
• a metal, and
• an organic compound comprising a color changing part and a functional group,
• wherein the organic compound forms a coordination complex with the metal, and
• wherein the metal-organic framework comprises a complex represented by the following Chemical Formula 1 or Chemical Formula 2:
• wherein, in the above Chemical Formula 1 or Chemical Formula 2, M is a metal, ECM is an organic group which can be oxidized and reduced, L1 and L2 are each independently a single bond, a substituted or unsubstituted C1 to C30 alkylene group, a substituted or unsubstituted C3 to C30 cycloalkylene group, a halogen-containing group, or a combination thereof, X1 and X2 are each independently a functional group which forms a coordination complex with the metal, and n is 1 to about 5.

An electrochromic device comprising:

• a first electrode and a second electrode opposite the first electrode;
• an electrochromic layer disposed on the first electrode or the second electrode, the electrochromic layer comprising an electrochromic material;
• and
• an electrolyte disposed between the first electrode and the second electrode,
• wherein the electrochromic material comprises a metal-organic framework comprising a metal and an organic compound comprising a color changing part and a functional group, wherein the organic compound forms a coordination complex with the metal, and
• wherein the organic compound comprises a substituted or unsubstituted viologen, a substituted or unsubstituted anthraquinone, or a combination thereof.
