| Abstract: | Calixn]arenes represent an interestingclass of preorganized aromatic hostsexhibiting an enhanced ability forcation- interaction. Recent resultsobtained with the complexation of variouscalixn]arenes and five structural typesof organic cations, namely ammonium ions,quaternary ammonium ions, phosphonium ions,iminium ions and tropylium ions are reviewed.The influence of both the guest structure and theshape and flexibility of the hosts on the complexstability in the gas phase and (mainly) in solutionis considered. |
