Description
Summary:Herein, using the modulator synthesis approach, a zirconium-based metal–organic framework (Zr-MOF), [Zr6O4(OH)4L4(H2O)2(HCOO)4]·9DMF·12H2O (JLU-MOF50, L = H2MDCPB = 5′-methyl-[1,1′,3′,1′′-terphenyl]-4,4′′-dicarboxylic acid, DMF = N,N-dimethylformamide), with pcu topology was successfully synthesized and structurally characterized. JLU-MOF50 exhibits excellent chemical stability in both acidic and alkaline aqueous solutions. Due to the missing linker sites, high porosity (BET surface area of 1101 m2 g−1), and excellent luminescence property, JLU-MOF50 possesses dual functionalities, which exhibits not only a commendable trapping capacity (92 mg g−1) and an adsorption rate (32.5 mg g−1 min−1), but also high detection sensitivity and selectivity for Cr2O72− in an aqueous phase. It is worth mentioning that the KSV value of JLU-MOF50 towards Cr2O72− can reach up to 4.99 × 104 M−1, which is one of the highest values reported to date for MOF materials. Based on the aforementioned properties, JLU-MOF50 is a good candidate for fast capture and highly luminescence detection of Cr2O72− simultaneously in an aqueous phase.
