Özet

Synthesis of a new coumarin-triazole-based dye and its photophysical parameters such as absorption, fluorescence emission, and fluorescence quantum yield were investigated. Studies have shown that the present dye has symmetry with a mirror image, especially in the ethanol solvent, with respect to the absorption and fluorescence spectra. As a result of the UV-vis and fluorescence spectroscopy techniques used, it was determined that absorption and emission spectra were shifted to the red with increasing solvent polarity. In addition, the spectral data of the synthesized compound exhibited that the stokes shifts are small, usually less than 50 nm, and the quantum yields are significantly high. In accordance with the results obtained, it can be stated that this novel dye synthesized here can offer an insight into application in sensor applications as analytical or biosensors, optoelectronic devices, and medicine industry.
