Abstract
There are three chapters in the thesis. The cooperative and selective lithium complexation of compounds 3 and 6 containing urea groups was discussed in the chapter 1. Compounds 3 and 6 form 1:2 complex with lithium ion cooperatively. The selective lithium complexation of compound 6 among ions belong to IA was found from fluorescence experiment.
Urea and amide were used as guest molecule in the chapter 2. Dicarboxylate 36 shows three anodic waves and two cathodic waves in CV. The cathodic current decreased when urea and amide were added. The linear relationship of the concentration of analyte and 36, Ipc0 and Ipce was followed the equation below:[Analyte]/[36]0-{(Ipc0-Ipce)/Ipc0}=(1/K[36]0) {(Ipc0-Ipce)/Ipc0},the slope is binding constant K.
The synthesis of cyclic chiral compounds R-56, S-56 and 79 containing urea groups was discussed in chapter 3.
