中文摘要	sodium ion transfer across micro-water/1,2-dichloroethane (dce) interface facilitated by a novel ionophore, terminal-vinyl liquid crystal crown ether (lcce) was studied by cyclic voltammetry. lcces have potential applications because of their physicochemical properties and the utilization of crown ethers as selective ionophoric units in other functionalized compounds are interesting. host-guest-type behavior for such compounds in the liquid-crystalline state is studied. the experimental results suggest that the transfer of the sodium ion facilitated by lcce was controlled by diffusion of lcce from bulk solution of dce to the interface. the diffusion coefficient of lcce in dce was calculated to be equal to (3.62 +/- 0.20) x 10(-6) cm(2)/s. steady-state voltammograms are due to sodium ion transfer facilitated by the formation of 1: 1 metal (m)-lcce complex at the interface and the mechanism tends to be transfer by interfacial complexation or dissociation (tic or tid). the stability constant of the complex formed was determined to be log beta(o) = 5.5 in dce phase. the influence of parameters such as concentration of sodium ion and concentration of lcce on the sodium ion transfer was investigated.
