Abstract
란탄나이드 3가 [Sm(Ⅲ), Tb(Ⅲ), and Yb(Ⅲ)]와 유기리간드들의 착물을 비수용매 속에서 전기화학적인 DC 및 DP 폴라로그래피 그리고 CV방법으로 조사하였다. 란탄나이드 3가 착물들은 Ag/AgCl 전극에서 이들 환원 peak는 Epc = -0.16 V, -0.35 V, -0.14 V와 그리고 -0.03 V의 비가역적인 일전자환원 과정이었고, 무거운 란탄나이드의 거동은 원자번호가 증가함에 따라서 안정도상수는 Sm > Tb > Ho > Yb순서로 감소하였다.

The electrochemical behavir of trivalent lanthanides [Sm(Ⅲ), Tb(Ⅲ), and Yb(Ⅲ)) complexes were investigated by the use of direct current, differential pulse polarography and cyclic voltammetry in aprotic media. These reduction peak were irreversible one-electron processes at Epc = -0.16 V, -0.35 V, -0.14 V, and -0.03 V of trivalent lanthanide complexes vs. Ag/AgCl electrode and the behavior of heavier lanthanides were decreased Sm > Tb > Ho > Yb order of the stability constant with decreasing atomic number.
