Аннотация: Two new heptamethine cyanine dye–fullerene C₆₀ covalently- linked dyads, which absorb in far-red and NIR spectral regions, have been synthesized by esterification click reaction and characterized by physicochemical methods. No significant fluorescence quenching was found due to weak electronic coupling between heptamethine moiety and fullerene core, which was confirmed by photophysical and electrochemical methods. Such dyads can be useful for cell imaging and fluorescence diagnostics of various fullerene derivatives.

Ключевые слова: fullerene C₆₀, fullerene derivatives, heptamethine compounds, cyanine dyes, dyads, fluorescence, NIR absorbance.
