Effects of Concentration on Aggregation of BODIPY-Based Fluorescent Dyes Solution.

Despite significant progress in understanding of dye aggregation, there are still processes that need to be further explored and which can significantly affect aggregation. In this work it was shown that the aggregation of dyes is influenced not only by dye concentration, but also by solvent polarity. It was found that nature, positions and number of fluorescent peaks may be controlled by simultaneous varying of both water fraction and dye concentration.

Effect of π-Extended Substituents on Photophysical Properties of BODIPY Dyes in Solutions.

Four boron-dipyrrine (BODIPY) based dyes with π-extended substituents in 8-position of dipyrrin ligand have been synthesized and characterized. Photophysical properties of the obtained compounds have been investigated in different individual solvents. Deposits of solvent polarity and viscosity were evaluated.

Fluorescent Properties of 8-Substituted BODIPY Dyes: Influence of Solvent Effects.

Three boron-dipyrrine (BODIPY) based dyes with bulky substituents in 8-position of dipyrrin ligand have been synthesized and characterized. Photophysical properties of the obtained compounds have been investigated in different individual solvents and solvent mixtures. Investigated compounds was found to be intensive fluorescent molecular rotors.
