A 40-year search for a truly porous gmelinite zeolite (GME) is brought to an end with the discovery of CIT-9, thus allowing final benchmarking of GME for important hydrocarbon chemistries. The synthesis is exceptionally sensitive to the concentration of the organic structure serving as the directing agent, and its cis to trans isomerism, the latter of which was confirmed by molecular modelling.

CIT-9：无缺陷的斜纹沸石

CIT-9的发现结束了为期40年的对真正的多孔斜长方沸石沸石（GME）的搜索，从而使GME在重要烃化学领域的最终基准得以实现。该合成对用作引导剂的有机结构的浓度及其顺式对反式异构现象特别敏感，后者通过分子建模得到证实。
