Electrochromic compounds and associated media and devices
First Claim
1. An electrochromic device, comprising:
- a first substantially transparent substrate having an electrically conductive material associated therewith;
a second substrate having an electrically conductive material associated therewith; and
an electrochromic medium comprising;
at least one solvent;
at least one anodic electroactive material;
at least one cathodic electroactive material;
wherein at least one of the anodic and cathodic electroactive materials is electrochromic; and
wherein at least one anodic electroactive material is represented by the following formula;
wherein X comprises N—
R10, O, or S;
wherein R1-R10 are the same or different and comprise H, an alkyl, cycloalkyl, polycycloalkyl, heterocycloalkyl, aryl, alkaryl, aralkyl, alkoxy, alkenyl, and/or alkynyl group containing approximately 1 to approximately 50 carbon atom(s) and/or a silyl or siloxyl group containing approximately 1 to approximately 50 silicon atom(s), wherein the carbon and/or silicon atom(s) may be a linking group to, or part of, a halogen, a N, O, and/or S containing moiety, and/or one or more functional groups comprising alcohols, esters, ammonium salts, phosphonium salts, and combinations thereof;
with the proviso that at least one of R5 and R10 comprises an alkyl, cycloalkyl, polycycloalkyl, heterocycloalkyl, aryl, alkaryl, aralkyl, alkoxy, alkenyl, and/or alkynyl group containing 4 to approximately 50 carbon atoms, wherein at least one of the carbon atoms may be a linking group to, or part of, a halogen, a N, O, and/or S containing moiety, and/or one or more functional groups comprising alcohols, esters, ammonium salts, phosphonium salts, and combinations thereof, and wherein at least one of R5 and R10 is void of any β
hydrogen atoms.
