Patent ID: 7456281

Claim:
A compound having the formula: wherein the moiety represents an optionally-substituted fused monocyclic or polycyclic aromatic ring or an optionally-substituted fused monocyclic or polycyclic nitrogen-containing heteroaromatic ring; X is oxygen, sulfur, selenium, tellurium or a moiety selected from C(CH 3 ) 2 and NR 1 , where R 1 is hydrogen or C 1-6 alkyl; R 2 is selected from the group consisting of C 1-6 alkyl, C 3-8 cycloalkyl, aryl, aryl(C 1-3 alkyl), hydroxyalkyl, alkoxyalkyl, aminoalkyl, mono and dialkylaminoalkyl, trialkylammoniumalkyl, alkylenecarboxylate, alkylenecarboxamide, alkylenesulfonate, optionally substituted cyclic heteroatom-containing moieties, and optionally substituted acyclic heteroatom-containing moieties; t=0 or 1; Z is a charge selected from 0 or 1; R 3 is selected from the group consisting of hydrogen, C 1-6 alkyl, and arylcarbonyl, or R 2 and R 3 are taken together to form —CH 2 ) w —, wherein w is 1 to 5; R 9 and R 10 are each independently selected from the group consisting of hydrogen, C 1-6 alkyl, and arylcarbonyl; n=0, 1, or 2; and v=0 or 1; with the proviso that v=0 when R 2 and R 3 are not taken together to form —(CH 2 ) w —; wherein when v=0, Q is an heterocycle selected from the group of structures consisting of: and wherein when v=1, Q is an heterocycle selected from the group of structures consisting of: wherein R 4 , R 5 , R 6 , R 7 , R 8 , R 12 , and R 13 are independently selected from the group consisting of hydrogen, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, alkenyl, polyalkenyl, alkynyl, polyalkynyl, alkenylalkynyl, alkylnitrilethio, aryl, heteroaryl, alkoxy, arylcarbonylthio, cycloheteroalkylcarbonylthio, dialkylaminoalkylcarbonylthio, dialkylamino, cycloalkylthio, cycloheteroalkylthio, trialkylammoniumalkylthio, trialkylammoniumalkylcarbonylthio, and nucleosidylthio, each of which may be optionally substituted; an acyclic heteroatom-containing moiety, a cyclic heteroatom-containing moiety, a BRIDGE-DYE, and a reactive group, each of which optionally includes a quaternary ammonium moiety.
