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.  </span> <br />}, number={2}, publisher={Turkish Chemical Society}
