In this study, a novel highly emissive compound
was synthesized via two steps synthetic procedure and characterized by 1H-NMR,
13C-NMR and FTIR. Then its photophysical properties, pH sensing behaviours
and pH-dependent hydrolysis were systematically investigated by ultraviolet and
fluorescence spectroscopy. Photophysics studies were carried out in fourteen
common organic solvents and absorption/emission spectra were recorded in Britton Robinson buffers (pH=3-12) to determine pH sensing behaviours. From
the photophysical results, it has been shown that the novel compound exhibits
strongly solvent polarity dependent emission and has high quantum yield (up to
0.72). Furthermore, at pH=12, absorbance started to decrease while emission was
increasing and blue-shifting due to basic hydrolysis after a several minutes. Therefore,
time dependent hydrolysis was also investigated at mentioned pH.
