Bottom-Up Fabrication of Ultrathin 2D Zr Metal–Organic Framework Nanosheets through a Facile Continuous Microdroplet Flow Reaction
关键字：MOF, Microdroplets
Direct synthesis of the ultrathin and discrete 2D metal-organic framework (MOF) nanosheets is extremely challenging. Herein, we present the first facile continuous bottom-up strategy
for preparing ultrathin (～3 nm) 2D MOF nanosheets with high crystallinity comprising assemblies of a few layers. Unlike conventional solvothermal synthetic methods for 2D MOFs, the weak interlayer interaction ...

A Heterotetranuclear Metal Complex {Ni2Na2} with Azido Bridges
关键字：Heterotetranuclear, Defective dicubane, Solvothermal synthesis,Magnetic properties
The reaction of Ni(ClO4)2·6H2O with 3-ethoxy-2-hydroxybenzaldehyde
(Hemp), methylamine, and NaN3 in DMF solution, under solvothermal conditions, leads to the formation of the heterotetrametallic cluster [Ni2Na2(μ1,1,1-N3)2(emimp)4(DMF)2] (I) (emimp = 2-ethoxy-6-formyl-phenolate anion, DMF = N,N-dimethyl-formamide). Compound I displays dominant ferromagnetic interactions through μ1,1,1-N3 bridg...
