Abstract
The boron-dipyrromethene (BODIPY) dye containing an annelated cyclohexyl rings at the 2,3 and 5,6-positions of pyrroles has been synthesized and characterized. Photochemical properties of the obtained compound have been investigated in different individual solvents. 2,3;5,6-Bis(cyclohexano)-BODIPY exhibits intense chromophore properties with maximum of S o → S 1 band in the 543-549 nm (A from 66000 to 96000 L/mol·cm). The complex is a fluorophore with a quantum yield up to ~ 100%. The influence of solvent polarity on the spectral properties was evaluated. To better understand the spectroscopic results, quantum chemical calculations were carried out. Photostability of dye was studied.Graphical Abstract.Entities:
