Quick on the uptake: Following its identification during a targeted search, the intriguing crystal structure of 3,3',4,4'-tetra(trimethylsilylethynyl)biphenyl was investigated. Simple removal of the included solvent provides an organic crystal with an open microporous structure that has a striking similarity to that of zeolite A (see picture). Reversible adsorption of nitrogen and hydrogen gases at 77 K confirms that the microporosity is permanent.
在一次定向搜索中发现其结构后,对3,3',4,4'-四(三甲基硅乙炔基)联苯有趣的晶体结构进行了研究。简单地除去其中所含的溶剂,就得到了一种具有开放微孔结构的有机晶体,该结构与A型沸石的结构有着惊人的相似之处(见图)。在77 K下对氮气和氢气的可逆吸附证实了微孔的永久性。
