Adsorption-based xylene isomer separation is more energy efficient than conventional processes. Herein, three isostructural Hofmann-type porous coordination polymers (PCPs), {M(Pz)[Ni(CN)4]n} (M = Fe, FePzNi, Co, CoPzNi, and Ni, NiPzNi; Pz = pyrazine) were synthesized and shown to exhibit coordination-dependent lability for the selectivity toward p-xylene over m- and o-xylene.
基于吸附的二甲苯异构体分离比传统工艺更节能。在此，合成了三种同构的霍夫曼型多孔配位聚合物（PCPs），{M(Pz)[Ni(CN)₄]ₙ}（M = Fe、FePzNi、Co、CoPzNi和Ni、NiPzNi；Pz = 吡嗪），并表明它们对p-二甲苯相对于m-二甲苯和o-二甲苯的选择性表现出配位依赖性不稳定性。
