Abstract
ENGLISH ABSTRACT: A number of porous metal-organic and organic crystalline materials were prepared with a view to study the solid-state dynamics involved in sorption and guest-exchange processes. The main goal was to gain an understanding of the mechanisms involved in structural changes induced by external stimuli. To this end, single-crystal X-ray diffraction (SCD) experiments were carried out under variable temperature and pressure conditions, supplemented by thermal analysis and sorption experiments.
AFRIKAANSE OPSOMMING: 'n Aantal poreuse metaal-organiese en organiese kristallyne materiale is berei met die doel om die vaste-toestand dinamika wat betrokke is in sorpsie en gas-uitruil (E. guest-exchange) prosesse te ondersoek. Die hoofdoel is om 'n begrip van die meganismes wat betrokke is in die strukturele veranderinge veroorsaak deur eksterne stimuli, te verkry. Dus is enkel-kristal X-straal-diffraksie eksperimente uitgevoer onder verskeie temperatuur- en drukkondisies. Die X-straal diffraksie eksperimente is aangevul deur termo-analise (E. thermal analysis) en sorpsie eksperimente.
