The degradation ofJ-aggregates of thiacarbocyanine dye (THIATS) exposed to visible radiation is experimentally investigated. A model that allows a consistent description of photodegradation ofJ-aggregates in a solution is proposed. Luminescence quenc

The experimental absorption spectra of J-aggregates of the carbocyanine dye THIATS and TDC were fitted to a segment and a continuous energy disorder (CED) model. From 6 K to room temperature the best fits were obtained using an exponential distributi

Exciton relaxation processes in J-aggregates of 3,3′,9-triethyl-5,5′-dichlorothiacarbocyanine iodide (TDC) dye have been studied by means of site-selective, steady-state and time-resolved spectroscopy. We found that TDC forms three different type

A negative fluorescence anisotropy is observed in J-aggregates of two thiacarbocyanine dyes in water-ethylene glycol low-temperature glass upon excitation outside the J-band. The fluoresence anisotropy gradually increases from −0.16 upon non-resona
