and its zinc complexes were synthesized. Its structure was investigated by MS
elemental analysis
FTIR spectra
TG-DTG curve; through UV-Vis absorption spectroscopy
fluorescence excitation and emission spectra the photophysical properties of the complexes were studied. The results showed that the ZnL's thermal decomposition temperature was 433.2 ℃
with very good thermal stability; in DMF solution system
the UV absorption band of ZnL complex was in the ranges of 250~500 nm
with fluorescence excitation in the ranges of 343~493 nm. The orange-red fluorescence emission peak wavelength was at 626 nm
the best excitation wavelength was 470 nm
and the band gap was 2.32 eV.
