The protonation constants of a set of solvatochromic pyridinium-N-phenolate betaine dyes I–XI (D±) were determined in methanol, water, and the ternary solvent mixture benzene – ethanol – water (with mass ratio 47:47:6) ...

The behavior of a reporter molecule, the solvatochromic dye 2,6-dichloro-4(2,4,6-triphenylpyridinium-1-yl)phenolate, was studied in aqueous micellar solutions of anionic, nonionic, and cationic surfactants. The possibility ...

The properties of SiO₂ nanoparticles interface modified with cationic surfactant molecules has been studied. Using a fluorescent indicator 2,7-dichlorofluorescein as the surface probe, it has been demonstrated that a bilayer ...
