The specification discloses quenchers of excited state energy, probes and other conjugates comprising the same, and methods for their use. The quenchers of excited state energy have a structure comprising at least one reactive functional group for linking the quencher to a carrier molecule, and at least three radicals covalently linked via exocyclic diazo bonds, the at least three radicals including at least one comprising a julolidine of the nominal formula (I), and the remainder of the at least three radicals being selected from the group of substituted and unsubstituted aryls, substituted and unsubstituted heteroaryls, and combinations thereof. |
