Patent ID: 8158444

Claim:
A multichromophore complex comprising: a multichromophore covalently bound by a unique bioconjugation site pendant to at least one biomolecule selected from the group consisting of a sensor biomolecule, a bioconjugate and a target biomolecule wherein the multichromophore is used as a reporter or further comprises a signaling chromophore covalently bound to the multichromophore or the biomolecule; wherein the multichromophore comprises the structure wherein m, n and p are ≧1 wherein each R 1 is independently an ethylene glycol oligomer or ethylene glycol polymer; wherein 1, 2 and 3 are 7-conjugated units independently selected from the group consisting of benzene, naphthalene, anthracene, fluorene, indenofluorene, thiophene, thienothiophene, dithienothiophene, 3,4-ethylenedioxythiophene, furan, pyridine, pyrrole, fused pyrrole, tetrahydropyrene and oxadiazole, each optionally substituted, and wherein 2 and/or 3 comprise one or more said unique bioconjugation sites, linked by a linker and wherein 1, 2 and 3 can optionally be angled π-conjugated linkers in the π-conjugated backbone.
