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.

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
