The host H, 9,9’-(ethyne-1,2-diyl)bis(fluoren-9-ol), has been employed to study its selectivity towards the close boiling alcohol pair, 2-propanol and tertiary butanol. H is selective for tertiary butanol at low temperatures, but includes both guests without discrimination at high temperatures. Concomitantly higher Guest/Host ratios were observed at lower temperatures, in agreement with the literature. The kinetics of solid-host: guest-vapour enclathration was successfully measured by powder X-ray diffraction.

主体客体化合物化学计量的结晶温度控制和选择性

宿主H，9,9'-（乙炔-1,2-二基）双（芴-9-醇），已被用于研究其对接近沸腾的醇对，2-丙醇和叔丁醇的选择性。H在低温下对叔丁醇具有选择性，但在高温下对两种客体均无区别。与文献一致，在较低温度下观察到较高的客体/宿主比。通过粉末X射线衍射成功地测量了固体-主体：客体蒸气包合的动力学。
