摘要： 用循环伏安法研究新型载体端烯基液晶冠醚推动钠离子的转移,结果表明,钠离子的转移由扩散控制.探讨了影响钠离子转移的因素,如端烯基液晶冠醚和钠离子的浓度等.求算出端烯基液晶冠醚在1,2-二氯乙烷中的扩散系数为(2.61±0.12)×10-6cm2/s,端烯基液晶冠醚和钠离子在1,2-二氯乙烷中所形成的配合物稳定常数lgβo=5.7.

Abstract: The sodium ion transfer across the micro water/1,2-dichloroethane interface facilitated by a novel ionophore, liquid crystal crown ether was studied systematically. The sodium ion transfer facilitated by LCCEis controlled by diffusion studied by cyclic voltammetry. The diffusion coefficient of LCC-Ein-1,2-dichloroethane was calculated to be equal to (2.61±0.12)×10-6 cm2/s and the stability constant of the complex between Na+ and LCCEwas determined as lg βo=5.7 in 1,2-dichloroethane.

Key words: Facilitated ion transfer, Micro liquid/liquid interface, Liquid crystal crown ether
