Preparation of a photostable tribrachia cyanine dye and its high chemical activity towards hydrosulfide

Viscosity probes towards different organelles with red emission based on an identical hemicyanine structure

“…The photostability of cyanine was generally poor, 34 while probes 1a-d belong to hemicyanine, so photostability experiments were performed in order to investigate their photostability. Due to its non-nucleophilic properties and good solubility, acetonitrile was chosen as the solvent to eliminate interference with photostability.…”

A novel mitochondrion-targeted fluorescent probe for detecting viscosity in living cells and zebrafishes

“…In recent years, due to the advantages of high selectivity and biocompatibility, simple labelling operations without further staining, and easy regulation of emission through molecular engineering, small molecular fluorescent probes have become one of the foundations of modern biological analysis and real-time bio imaging techniques. [17][18][19] Furthermore, the fluorescent probes have good temporal and spatial resolution. Therefore, they could be adapted to monitor viscosity changes at microscopic scales in real time.…”

Solvatochromism and halochromism of some furo/pyrazole cyanine dyes

“…Cyanine dyes (Shindy, 2016;Shindy, 2017;Shindy, 2018;Shindy, 2018a;Shindy, et al, 2019;Gorka and Schnermann, 2016;Liu, et al, 2017;Borisova, et al, 2018;Sha, et al, 2018;Cha, et al, 2011) are suitable compounds for studies of the colour of organic substances and fundamental principles exist relating colour to chemical structure and nature of the solvent (Venkataraman, 2012;West and Geddes, 1964;Derevyanko, et al, 1983;Ishchenko, et al, 1984;Ishchenko, et al, 1989). The pyrazole compounds find various industrial uses and applications (Shindy, et al, 2018).…”
