| abstract |
An organic colorant complex with the following general structure: ABn(DE)mTxQy, wherein A is an organic chromophore; B is an electrophilic reactive group covalently bonded to A directly or through a linking group; D is a nucleophilic linking group covalently bonding B and E, selected from the group consisting of NR, O, S, and 4-oxyanilino (--HN--Ph--O--); wherein R is selected from the group consisting of H, alkyl, aryl, and E; E is an organic alkyl and aryl group or an end group; T is an ionic group covalently linked to A; Q is an organic cation, bonded to the organic chromophore A through ionic interaction with T; n, m, x, and y are independent integers from 1 to 10. |
