Water-soluble BODIPY and aza-BODIPY dyes: synthetic progress and applications

Gang FAN,Le YANG,Zhijian CHEN

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 4,   Pages 405-417 doi: 10.1007/s11705-014-1445-7

Abstract: In recent years, boron-dipyrromethene (BODIPY) and boron-azadipyrromethene (aza-BODIPY) dyes have attracted considerable multidisciplinary attention due to their diverse applications. By introducing various hydrophilic groups, such as quaternary ammonium, sulfonate or oligo-ethyleneglycol moieties into the BODIPY core, the solubilities of these dyes in aqueous solution can be greatly improved while maintaining their high fluorescence quantum yields. Accordingly, applying these fluorescent dyes in aqueous systems to areas such as chemosensors, biomacromolecule labeling, bio-imaging and photodynamic therapy has been achieved. In this article, the recent progress on the synthesis, optical properties and application of water-soluble BODIPY dyes and aza-BODIPY dyes is reviewed.
