Aggregation in xanthene dyes, exciton emission and phosphorescence enhancement
TLDR
In this paper, aggregate emission and absorption spectra have been studied in fluorescein, eosin and erythrosin in glycerol water frozen glass, and exciton splitting is also calculated using exciton model for non-crystalline aggregates.About:

Dye aggregation in dye-sensitized solar cells
Lei Zhang,Jacqueline M. Cole +1 more
TL;DR: In this article, the molecular origins of dye aggregation, manifestations of hypsochromic (H) and bathochromic (J) dye aggregation in DSSCs, and ways by which dye aggregation can be suppressed in cases where it is undesirable.

Direct and sensitized photooxidation of cyanine dyes.
TL;DR: Direct photooxidation of cyanine dyes was found to be markedly enhanced by formation of hypsochromically shifted (H) aggregates bysinglet oxygen attack on 3,3′‐diethyl‐8,10‐dimethylthiacarbocyanine yields carbonyl products consistent with 1,2 addition to the 2,8 bond of the methine chain.

Excited state (excitation) interactions in polyene aggregates. Resonance Raman and absorption spectroscopic evidence
TL;DR: In this article, the resonance Raman spectra of carotenoids were used for detecting excited state perturbations. And the results of the resonance analysis showed that strong excited state interactions are taking place and these results illustrate the utility of the Resonance Raman technique for recognizing excited state.

Erythrosin B Phosphorescence Monitors Molecular Mobility and Dynamic Site Heterogeneity in Amorphous Sucrose
TL;DR: The use of steady-state and time-resolved phosphorescence of erythrosin B to monitor mobility in thin films of amorphous solid sucrose provides evidence of the value of phosphorescence as a probe of dynamic site heterogeneity as well as overall molecular mobility in isorphous biomaterials.

Deciphering the Structure–Property Relations in Substituted Heptamethine Cyanines
TL;DR: The combination of experimental results with quantum-chemical calculations provides insights into the structure-property relationship, the elucidation of which will accelerate the development of cyanines with properties tailored for specific applications, such as fluorescent probes and sensors, photouncaging, photodynamic therapy, or singlet-oxygen detection.
