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<sub>2</sub>(oba)<sub>2</sub>(4-bpdb)]<sub><i>n</i></sub>·2­(DMF) (TMU-4), [Zn­(oba)­(4-bpdh)<sub>0.5</sub>]<sub><i>n</i></sub>·1.5­(DMF) (TMU-5), and [Zn­(oba)­(4-bpmb)<sub>0.5</sub>]<sub><i>n</i></sub> 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.
