| Abstract: | A comparative study on the spectroscopy and photo-physical behavior of differential substituted pyrazoline has been carried out in this work. Results indicate that the change of the elec- tronic donating and withdrawing ability of the substitution group attached at the 3-positopon on the pyrazoline ring effectes strongly on the fluorescence quantum yield and the fluorescence quenching of these compounds. This is determined by the structural characterization of pyrazoline compounds. The Phenomenon described above is discussed in detail in this paper. |
