Abstract

Thiazolothiazoles (TzTz) represent a class of compounds with distinctive structural motifs and exceptional optical properties, positioning them as promising candidates for breakthroughs in optoelectronic and sensing technologies. X-ray crystallographic analyses of TzTz units symmetrically substituted with functional groups such as imidazole, o-vanillin, p-vanillin, phenyl, thiazole, cinnamate, and bistrifluoromethylphenyl have revealed complex structural features, including {\pi}-{\pi} stacking interactions, hydrogen-bond networks, and specific chalcogen and halogen interactions. These interactions collectively enhance the stability and define the unique spectroscopic profiles of these compounds. Beyond classical spectral fingerprints (FTIR, NMR, and UV-Vis spectra), fluorescence studies at various temperatures, complemented by XANES synchrotron analyses, have underscored their remarkable thermal and electronic properties. The findings presented here offer a comprehensive framework for the characterization and analysis of TzTz compounds, emphasizing their potential as components in smart electronic and optoelectronic devices.
