Abstract
각종 아민과 할로겐화합물간의 Charge Transfer Complex 형성여부를 검토하여 보았다. Pyridine Tridthylamine, Piperidine Ethanolamine Triethanolamine, Aniline, Diethylamine 등의 아민류와 사염화탄소 또는 클로로폼의 혼합용액을 n-Hexane 용매존재하에서 자외선흡수 스펙트라를 검사한 결과 장파장쪽의 Shift가 있었으며 특히 Diethylamine과 Triethylamine은 클로로폼 또는 사염화탄소와 1:1 Charge Transfer Complex를 형성하였고, Piperidine은 접촉적 Complex를 형성하는 것이 확인되었다. Complex의 형성경향과 아민의 Nucleophilicity와의 관계를 논의하였다.

The formation of a charge transfer complex between various amines and organic halogen compounds was closely investigated. A mixture of amine (piperidine, pyridine, diethylamine, ethylamine, triethylamine and triethanolamine) and organic halides(carbon tetrachloride and chloroform) was checked for its UV absorption spectrum in presence of n-hexane solvent. A red shift was observed. The formation of charge transfer complex was observed in the case of triethylamine and diethylamine, whereas the formation of contact complex was distinct in case of piperidine. The relation between the nucleophilicity of amines and their tendency of forming charge transfer complex was discussed.
