A method of imaging using selective fluorescent emitters and compositions for imaging are described. The method can include contacting a specimen with a composition comprising at least one selective fluorescent emitter of Formulas (I) through (IX) and irradiating the specimen with an excitation wavelength. The fluorescence emitted by the selective fluorescent emitter can be detected to generate an image. Formulas (I) through (IX) are: (I), (II), (III), (IV), (V), (VI), (VII), (VIII), (IX) wherein: R1 = OR4 or NR3R4; R2 = OR4, NR3R4, Cl, F or H; R3 = H, CH3, C2H5, C3H7 or C4H9; R4 = H, CH3, C2H5, C3H7 or C4H9; R5 = H or CH2(CH2)nNR3R4; R6 = H or CH2(CH2)n NR3R4; R7 = OR4, NR3R4, Cl, F or H; R8 = N-methyl pyridinium or N-methyl-l,2,3,6-tetrahydropyridine; and n = 1, 2 or 3. |
