The spectral and kinetic characteristics of the dye Sbt ((E)-2-(4-(dimethylamino)styryl)-3-methylbenzo[d]thiazol-3-ium iodide) and its homodimers Dbt-5, Dbt-10 in chloroform and its binary mixtures with solvents of different polarity were studied. It was found that with an increase in the proportion of hexane in chloroform solutions of the studied dyes, non-fluorescent H-aggregates are formed. It was found that the spectral and photophysical parameters of the studied dyes depend on the polarity and viscosity of the solvents. Quantum-chemical calculations of the charge distribution and potential energy in the ground and excited states for the molecules of the studied compounds were carried out. Sbt and Dbt-10 dyes are characterized by higher values of quantum yields and lifetime of the excited state in a viscous medium, which is associated with the formation of the TICT (twisted intramolecular charge transfer) state. The transition of molecules to this state leads to effective quenching of fluorescence.
