Abstract

Three new metal-organic framework isomers have been synthesized by using the organic linker 5-triazole isophthalic acid and Mn(NO(3))(2)·xH(2)O. Structural conversions from non-porous to porous MOFs due to the template effect have been observed. The cross-sectional pore apertures of the resulting Mn-MOFs are comparable to the molecular dimensions of the template (pyrazine and 4,4'-bipyridine). The periodic increased porosity in Mn-MOFs depending on the size of the template used has been further confirmed by the CO(2) adsorption isotherms.

摘要

三种新的金属有机骨架异构体已通过使用有机连接体 5-三唑间苯二甲酸和 Mn(NO(3))(2)·xH(2)O 合成。由于模板效应，已经观察到从非多孔到多孔 MOFs 的结构转换。所得 Mn-MOFs 的横截面孔径与模板（吡嗪和 4,4'-联吡啶）的分子尺寸相当。通过 CO(2)吸附等温线进一步证实了 Mn-MOFs 中周期性增加的孔隙率取决于所用模板的大小。
