Abstract

Charge transfer complexes of some electron donors with one electron acceptor have been studied to investigate the maximum absorption wavelength and absorbance by UV-Vis spectrometer in three kinds of solvents, such as ethylene chloride, methylene chloride, and chloroform, at the temperature ranges of 16∼25$^{\circ}$C. 1,2,3,4-Tetrahydrocarbazole (THC), 2-methyl, 3-methyl, and 3-ethyl THC were selected as electron donors while chloranil was used as an electron acceptor in this study. It is found that these complexes forms 1 : 1 complexes, and their maximum absorbance and formation constants decreases with respect to the function of the polarity of solvent and temperature. The polarity of solvents and the temperature have been influenced on the formation constants, which were described using the thermodynamic properties. Moreover, the electronic and steric effects of electron donors have also been effects.

몇 가지의 전자주개와 하나의 전자받개와의 전하이동 착물에 관한 연구는 세 종류의 용매 즉, 염화에틸렌, 염화메틸렌 그리고 클로로포름하에서 그리고 16, 19, 22, 25$^{\circ}$C의 온도범위에서 자외선 분광광도계로서 최대흡수파장 및 흡광도를 측정하였다. 그리고 이 연구는 전자주개로서는 1,2,3,4-테트라하이드로카바졸, 2-메틸, 3-메틸 그리고 3-에킬사수소카바졸을 선택하였으며 전자받개로는 클로라닐을 이용하였다. 이 전하이동 착물은 1:1 몰비로 형성되었으며, 최대흡광도 및 형성상수는 용매의 극성과 온도에 따라 감소하였다. 열역학적 양으로서 용매의 극성과 온도가 형성상수에 미치는 영향을 논하였으며, 또한 몇 가지의 전자주개들의 전자 및 입체효과가 형성상수에 미치는 효과를 고찰하였다.
