1. An electrochromic material comprising a substituted-1,1-dioxo-thiopyran of the general structure I:
- wherein;
X is carbon, nitrogen, oxygen, or sulfur;
n is 0, 1 or 2;
R3 is independently an electron withdrawing group or a substituted or unsubstituted alky or aryl group;
R3 and R5 each independently represent a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group; and
R2 and R4 each independently represent hydrogen, or an electron withdrawing group, or a substituted or unsubstituted alkyl group,provided at least one of R1 through R5 comprises a carboxlate, saliclate, or phosphonate.
