摘要:

通过对一类吡唑啉衍生物(1-苯基-3-(N,N-二甲基氨基苯乙烯)-5-(4-N,N-二甲基氨基苯基)-2-吡唑啉)在不同溶剂中的光谱行为,研究了该衍生物和溶剂分子间的一般相互作用和特殊相互作用.发现利用吡唑啉溶液的荧光猝灭现象能对其和溶剂分子间不同相互作用问题提供有价值的信息.

Abstract:

The spectral behavior of pyrazoline derivative 1-phenyl-3-(4-N,N-dimethylaminostyryl)-5-(4-N.N-dimethylaminophenyl)-2-pyrazoline in various solvents have been studied. According to the results obtained the general effects and the specific effects of interaction between the molecule of this derivative and the solvents used were investigated. It was found that the fluorescence quenching of pyrazoline solution by different species can be used as a method for studying both general and specific interaction between pyrazoline derivative and molecule of solvents.

Key words: Pyrazoline derivative, Solute/Solvent interaction, Fluorescence quenching
