通过调节旋盖剂的原位形成，构建了两种新的棒填料金属有机框架（RPMOF）。在CPM‐s7中，羧酸盐连接剂将1D锰氧化物链向另外四个方向延伸，形成3D RPMOF。用更强的Lewis酸性Co2+取代Mn2+，导致易于水解的磺酸盐连接剂加速，导致硫酸盐离子的存在减少了四个羧酸盐延伸方向中的两个，从而形成了新的二维棒状填料CPM - s8。密度泛函理论计算和磁化测量揭示了CPM - s8的铁磁有序，这标志着探索二维RPMOF作为有效低维磁性材料的潜力。
Two new rod‐packing metal–organic frameworks (RPMOF) are constructed by regulating the in situ formation of the capping agent. In CPM‐s7, carboxylate linkers extend 1D manganese‐oxide chains in four additional directions, forming 3D RPMOF. The substitution of Mn2+with a stronger Lewis acidic Co2+, leads to an acceleration of the hydrolysis‐prone sulfonate linker, resulting in presence of sulfate ions to reduce two out of the four carboxylate‐extending directions, and thus forming a new 2D rod‐packing CPM‐s8. Density functional theory calculations and magnetization measurements reveal ferrimagnetic ordering of CPM‐s8, signifying the potential of exploring 2D RPMOF for effective low‐dimensional magnetic materials.
