Abstract:
1. A luminophore comprising a donor portion (D) in close association with an acceptor portion (A) sufficient for resonant energy transfer therebetween, wherein upon excitation by external electromagnetic radiation of a wavelength shorter than λ 1 , said luminophore emits luminophore radiation in the range of about 450 to about 1200 nm of a wavelength longer than λ 1 , with an emission lifetime t 1 and a quantum yield Q 1 , wherein when D is not in said close association with A, it absorbs radiation of a wavelength λ wherein when said donor portion is in said close association with A and is excited by electromagnetic radiation of wavelength shorter than λ wherein said luminophore is a chemical compound, wherein D is covalently linked to A, and has the formula:
