In this study, the newly synthesized non-centrosymmetric, 4-dimethylamino-3′-isothiocyanatochalcone (PKA) compound was presented. This compound belongs to the chalcone group, and its main purpose is to be used in biomedical imaging as a fluorescence dye. For this reason, the linear and nonlinear properties in solvents of different polarity were thoroughly studied. In accordance with the requirements...
A novel hemicyanine dye possessing donor-π-acceptor structure that features a fixed benzimidazole ring as an electron donor and pyridinium moiety as an electron acceptor was synthesized. The structure of the hemicyanine was elucidated by means of NMR and IR spectroscopy. The dye was studied using steady-state absorption and emission spectroscopy. The analysis of experimentally recorded spectra was...
