Shape Control of Zn(II) Metal-Organic Frameworks by Modulation Synthesis and Their Morphology-Dependent Catalytic Performance

Micro- and nanorods and plates of three porous Zn(II)-based metal-organic frameworks, [Zn-2(oba)(2)(4-bpdb)(n)center dot 2(DMF) (TMU-4), [Zn(oba) (4-bpdh)(0.5)](n)center dot 1.5(DMF) (TMU-5), and [Zn(oba)(4-bpmb)(0.5)](n) 1.5(DMF) (TMU-6) were synthesized by the coordination modulation method. The effects of concentration of modulator, temperature, and time of reaction on size and morphology have been investigated. Also, catalytic performance of TMU-5 nanosized metal-organic framework in Knoevenagel condensation reaction was evaluated.
