A microporous metal-organic framework, PCN-14, based on an anthracene derivative, 5,5'-(9,10-anthracenediyl)di-isophthalate (H4adip), was synthesized under solvothermal reaction conditions. X-ray single crystal analysis revealed that PCN-14 consists of nanoscopic cages suitable for gas storage. N2-adsorption studies of PCN-14 at 77 K reveal a Langmuir surface area of 2176 m2/g and a pore volume of 0.87 cm3/g. Methane adsorption studies at 290 K and 35 bar show that PCN-14 exhibits an absolute methane-adsorption capacity of 230 v/v, 28% higher than the DOE target (180 v/v) for methane storage.
基于蒽衍生物5,5'-(9,10-蒽二基)二间苯二甲酸(H4adip)的微孔金属有机框架PCN-14在溶剂热反应条件下合成。X射线单晶分析表明，PCN-14由适合气体存储的纳米级笼子组成。PCN-14在77 K下的N2吸附研究表明，其Langmuir表面积为2176 m2/g，孔体积为0.87 cm3/g。在290 K和35 bar下的甲烷吸附研究表明，PCN-14的绝对甲烷吸附容量为230 v/v，比美国能源部甲烷存储目标(180 v/v)高28%。
