new aryl-boron-substituted BODIPY and aza-BODIPY derivatives of singular importance. Most of these aryl-boron-substituted BODIPYs showed bright emission in the aqueous solution with significant aggregation-induced emission enhancement and high solid-state emission as a result of the restrictedrotation of the meso-phenyl group and boron-substituted aryl groups as well as the formation of J-type aggregates

This study presents a series of ultrafluorogenic BODIPY-Tz probes, employing a monochromophoric strategy to acheive broad-spectrum fluorogenicity and effective bioorthogonal cellular imaging. These probes showcase a unique turn-on pattern with BCN and TCO, pioneering dual-color live-cell imaging with a single probe.
and stepwise cyanation of BODIPYs using tetrabutylammonium cyanide was developed to give α-cyanated BODIPY derivatives. Characterization of optical and electrochemical properties of these dyes provides substantial enhancement of the electronaffinity, with a reduction potential and LUMO level as low as −0.04 V and −4.43 eV, respectively. Radical anions of these electron-deficient 3,5-dicyanated BODIPYs

Eleven formyl-containing BODIPY dyes were prepared by means of either the Liebeskind-Srogl cross-coupling reaction or the Vilsmeier reaction. These dyes were used as components in the Passerini reaction to give highly substituted BODIPY dyes. A joined spectroscopic and theoretical characterization of the synthesized compounds was conducted to unravel the impact of the structural rigidity/flexibility on the photophysical signatures. These dyes were tested as fluorescent trackers for phagocytosis. Additionally, they proved to be useful to stain different blood cells with an intense and stable signal at a very low exposure time.
