Abstract
A chromonic compound represented by one of the following general structures: wherein each R2 is independently selected from the group consisting of electron donating groups, electron withdrawing groups, and electron neutral groups, R3 is selected from the group consisting of substituted and unsubstituted heteroaromatic rings and substituted and unsubstituted heterocyclic rings, said rings being linked to the triazine group through a nitrogen atom within the ring of R3, and M+ is a noble or transition metal cation.
Claims19
A compound selected from a group consisting of the following structures:
- wherein
- each R2 is independently selected from the group consisting of hydrogen and substituted or unsubstituted alkyl groups,
- R3 is selected from the group consisting of substituted and unsubstituted heteroaromatic rings and substituted and unsubstituted heterocyclic rings, said rings being linked to the triazine group through a nitrogen atom within the of R3, and when R3, is a substituted or unsubstituted heteroaromatic ring and said substituted or unsubstituted heteroaromatic ring has a postive charge associated therewith, R3 has a counterion X− associated therewith,
- each M+ is a noble metal cation;
- and
- wherein the anionic and cation components of said structure are present at a molar ratio so as to result in an overall neutral charge.
A compound selected from a group consisting of the following structures:
- wherein
- each R2 is independently selected from the group consisting of hydrogen, unsubstituted alkyl groups, alkyl groups substituted with a hydroxy or halide functional group, and alkyl groups comprising an ether, ester, or sulfonyl moiety;
- R3 is a substituted or unsubstituted heteroaromatic ring selected from the group consisting of substituted or unsubstituted pyridine, pyridazine, pyrimidine, pyrazine, imidazole, oxazole, isoxazole, thiazole, oxadiazole, thiadiazole, pyrazole, triazole, triazine, quinoline, and isoquinoline, and when said substituted, or unsubstituted heteroaromatic ring has a positive charge associated therewith, R3 has a counterion X− associated therewith;
- each M+ is a noble metal cation;
- and
- wherein the anionic and cation components of said structure are present at a molar ratio so as to result in an overall neutral charge.
A compound of the following structure:
- wherein
- M+ is a metal cation selected from the group consisting of a Ag action, a Au cation and a Pt cation;
- and.
- wherein the anionic and cation components of said structure are present at a molar ratio so as to result in an overall neutral charge.
