Two types of zinc MOF, Zn-X2Trp and Zn-X2PET (X=H, F, Cl, Br, I, Me, Et, Pr), with difunctionalized triptycene-hexacarboxylate ligands H6X2Trp and H6X2PET that differ in size have been synthesized. All of these Zn-MOFs show high thermal stability as well as H2- and CO2-adsorption capacities. Moreover, MOFs with smaller pore size showed higher H2 and CO2 adsorption. Thus, the introduction of methyl
两种类型的锌 MOF、Zn-X 2 Trp 和 Zn-X 2 PET(X=H、F、Cl、Br、I、Me、Et、Pr),具有双官能化三蝶烯-六羧酸酯配体 H 6 X 2 Trp 和 H已合成尺寸不同的6 X 2 PET。所有这些Zn-MOF 均表现出高热稳定性以及H 2 - 和CO 2 -吸附能力。此外,孔径较小的MOF表现出较高的H 2和CO 2吸附能力。因此,在三蝶烯配体的桥头位置引入甲基、氯和溴取代基增强了H 2 -和CO 2 -吸附能力。
