An efficient synthesis approach to unsymmetrical water-soluble cyanine dyes has been established. Loading and activation of sulfoindolenium to poly(ethyleneglycol) (PEG) have been achieved via a simple strategy. Cyanine dyes are released by the attack of heterocyclic carbon nucleophile and the cleavage of PEG-bound hemicyanine. The efficient approach delivers cyanine dyes in high purity without the

The synthesis, fluorogenic characterization, and labeling application of four tetrazine-quenched cyanine probes with emission maxima in the red–far red range is reported. Fluorescence of the cyanine-cores is quenched via through-bond-energy-transfer (TBET) exerted by a bioorthogonal tetrazine unit. Upon bioorthogonal labeling reaction with cyclooctyne tagged proteins, the quenching effect ceases, and
Dyes and photoluminescent compounds based on polymethine dyes that contain at least one alkyl-phosphonate or substituted alkyl-phosphonate group, including the synthetic precursors, methods of synthesis, and applications thereof. Certain embodiments include heterocyclic ring systems and polymethine linkage are selected such that the resulting polymethine dye is a cyanine dye, a merocyanine dye, or a styryl dye.
