Abstract

This thesis reports an investigation of the synthesis and properties of a series of electrically active crown ethers and cryptand complexes. The work has fallen into a number of distinct categories: (i) The synthesis of and structural studies on an ion-binding ferrocene-bridged cryptand in which the ferrocene unit as a potential redox centre has been investigated. The ion-binding abilities of andselectivities shown by these materials have been established by a variety of chemical and spectroscopic techniques. The results obtained have been compared with their receptor cavity sizes as established by X-ray structural studies. There is no spectroscopic evidence for any direct interaction between the iron atom and a metal ion residing in the cryptand cavity. (ii) The effect of crown ether or cryptand encapsulation of a metal ion on the properties of some electrically active salts have been investigated. Two different types of material have been studies; (a) TCNQ salts which show metallic/semiconducting behaviour and (b) oxonol dye salts which are semi-insulators. It has been shown that the presence of crown ethers significantly modifies the electronic behaviour of these materialsand can cause a complete change in the dominant conduction mechanism. (iii) A series of substituted and polymeric crown ethers have been prepared and synthetic routes to a polymerisable cryptand have been explored. Polymeric crown ether/TCNQ salts are found to show similar electrical behaviour to that seen for the monomeric anaolgues.
