合成了两个py-官能化的bi双酰亚胺配体,用于制备双金属半三明治Ru(II)配合物。这些通过IR,1 H NMR,13 C CPMAS SSNMR光谱和元素分析来表征。络合物是轮轴(waa)化合物,其中轮轴是发散配体,而轮是[(p-cymene)RuCl 2 ]单元。络合物通过游离的固体/气体吸收而显示出挥发性有机化合物(例如甲苯和二甲苯)的吸收,而不是游离的配体。反应性可归因于waa几何形状,这可能是由于表征自由配体的结晶构架的高堆积的不安所致。确定摄取反应的动力学曲线。

The synthesis of a series of open U-shaped bis-porphyrin cavity molecules is described, with bridged bicyclic backbones to confer rigidity, and a pendant substituted aromatic probe unit suspended on the inside of the cavity. The dimensions and flexibility of the bis-zincporphyrin cavity were probed using several different techniques. Initially the molecular ruler concept was employed, using flexible bidentate ligands as guests with a range of possible linear dimensions. Secondly, NMR methods were employed with rigid bidentate ligand guests of fixed lengths, and thirdly diffusion based NMR methods were utilised. The range of inter-porphyrin distances estimated by these methods suggests that these types of open-cavity systems have a surprising degree of flexibility.
A method of purifying gaseous mixtures, for example ternary or quaternary gaseous mixtures, using a sorbent media comprising two or more sorbent materials. The method involves obtaining a target gas from a gaseous composition comprising the target gas, a first gas and a second gas, and optionally further gases by contacting the gaseous composition with the sorbent media to remove at least some of the first gas and at least some of the second gas from the gaseous composition. The sorbent media comprises at least a first sorbent material and a second sorbent material; wherein the first sorbent material has a higher adsorption selectivity for the first gas than for the target gas; and wherein the second sorbent material has a higher adsorption selectivity for the second gas than for target gas. The method may be particularly useful for the separation of pure ethylene, methane or propylene from such gaseous mixtures. A sorbent media and an apparatus for obtaining a target gas from such a gaseous composition are also disclosed.
