Abstract

The chemical behavior of trivalent lanthanide ($Pr^{3+}\;and\;Dy^{3+}$) and organo ligands (phen' and terpy') complexes was investigated by the use of UV/vis-spectrophotometric, magnetization and electrochemical method. The magnitude of crystal field splitting energy, the pairing energy and spin state was obtained from the spectra of complexes. These complexes were founded to be diamagnetics, delocalization and low spin complexes. The electrochemical behavior of complexes was observed by the use of cyclic voltammetry in aprotic media. These reduction peaks were irreversible two step reduction processes by electron transfer.

란탄나이드 3가($Pr^{3+}$ 와 $Dy^{3+}$)와 유기 리간드를 (phen', terpy') 착물들의 거동을 UV/vis 분광분석, 자기화 그리고 전기화학적 방법에 의해 조사하였다. 착물들의 결정장 갈라짐 에너지 크기와 짝지움에너지 그리고 스핀상태는 착물들의 스펙트라로부터 얻었다. 이들 착물들에 대한 전지화학적 거동은 비수용매속에서 순환 전압전류법에 의해 관찰하였다. 이들 환원피크는 전자 전이에 의한 비가역적인 2단계의 환원 과정이었다.
