Beschreibungen/Notizen

• 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. Based on structural analysis of newly synthesized 3D rod‐packing manganese‐based framework, strategic design of capping agent was developed to obtain a 2D rod‐packing framework. SQUID measurements and DFT calculations proved ferrimagnetic ordering of the material below 8 K, further illustrating the potential of developing spintronic materials through 2D rod‐packing MOFs
