The well-known MOF (metal-organic framework) linker tetrakis(p-benzoate)pyrene (TBAPy) lacks steric hindrance between its benzoates. Changing the 1,3,6,8-siting of benzoates in TBAPy to 4,5,9,10-siting introduces substantial steric hindrance and, in turn, enables the synthesis of a new hierarchically porous, she-type MOF Zr(μ-O)(μ-OH)(CHCOO)(COO)(TBAPy-2) (NU-601), where TBAPy-2 is the 4,5,9,10 isomer of TBAPy. NU-601 shows high catalytic activity for degradative hydrolysis of a simulant for G-type fluoro-phosphorus nerve agents.
著名的金属有机框架（MOF）连接体四（对苯甲酸）芘（TBAPy）的苯甲酸酯之间缺乏空间位阻。将TBAPy中苯甲酸酯的1,3,6,8位变为4,5,9,10位会引入大量空间位阻，进而能够合成一种新型的具有分级孔隙结构的片状MOF Zr(μ-O)(μ-OH)(CHCOO)(COO)(TBAPy-2)（NU-601），其中TBAPy-2是TBAPy的4,5,9,10异构体。NU-601对G型氟磷神经毒剂模拟物的降解水解表现出高催化活性。
