Electrochromic materials and electrochromic devices using the same

An electrochromic material comprising a compound of Formula 1:

• wherein R1 is selected from the group consisting of a single bond, a C6-C50 aryl group which is unsubstituted or substituted with at least one group selected from halo, hydroxyl, amino, cyano, nitro, thienyl, C1-C7 alkyl and C2-C7 alkenyl, a C5-C50 heteroaryl group which is unsubstituted or substituted with at least one group selected from halo, hydroxyl, amino, cyano, nitro, thienyl, C1-C7 alkyl and C2-C7 alkenyl, a thienyl group, a bithienyl group, a C2-C20 alkenyl group conjugated with at least one heteroatom selected from S and O or with the isophthalate groups at both ends thereof, a C2-C20 alkynyl group, a C3-C20 alkenylalkyl group, a C3-C20 alkynylalkyl group and a C4-C20 alkenylalkynyl group,
• wherein each R2 is independently —(CH2)m—, wherein m is an integer from 1 to 10, and
• wherein each R3 is independently selected from the group consisting of —CH═CH2, a C1-C10 linear, branched or cyclic alkyl group and a C2-C10 linear or branched alkenyl group.
