Photoswitching Mechanism of Cyanine Dyes
Cyanine dyes have been shown to undergo reversible photoswitching, where the fluorophore can be switched between a fluorescent state and a dark state upon illumination at different wavelengths. The photochemical mechanism by which switching occurs has yet to be elucidated. In this study, we have determined the mechanism of photoswitching by characterizing the kinetics of dark state formation an...
متن کاملGroove-binding unsymmetrical cyanine dyes for staining of DNA: syntheses and characterization of the DNA-binding.
Two new crescent-shaped unsymmetrical cyanine dyes have been synthesised and their interactions with DNA have been investigated by different spectroscopic methods. These dyes are analogues to a minor groove binding unsymmetrical cyanine dye, BEBO, recently reported by us. In this dye, the structure of the known intercalating cyanine dye BO was extended with a benzothiazole substituent. To inves...
متن کاملResearch on Syntheses and Properties of Water-soluble Symmetrical Squarylium Double-cyanine Dyes
In this paper, 2,3,3-trimethyl-3H-indolin was synthesized by phenylhydrazine and 3-methyl-2-butanone as raw materials in the acetic acid reacted with different nitrogenalkylating reagents. Semi mono-cyanine dye and semi dicyanine dye were prepared with the help of squaric acid diethyl ester. The spectral properties of the target products were checked. The results show that compared with symmetr...

In this paper, 2,3,3-trimethyl-3H-indolin was synthesised by phenylhydrazine and 3-methyl-2-butanone as raw materials in the acetic acid, and then was reacted with different nitrogen lkylating reagents. The two kinds of conducts acted with squaric diethyl ester respectively to prepare mono-semicynine dye and dis-semicyanine dye. The spectral properties of the target products were checked. The r...
متن کاملHeterobifunctional Dyes: Highly Fluorescent Linkers Based on Cyanine Dyes
Herein, we present a new synthetic route to cyanine-based heterobifunctional dyes and their application as fluorescent linkers between polymers and biomolecules. The synthesized compounds, designed in the visible spectral range, are equipped with two different reactive groups for highly selective conjugation under physiological conditions. By applying indolenine precursors with functionalized b...
