Structural and Electronic Studies of Substituted m-Terphenyl Group 12 Complexes

Andrew J. Valentine, Laurence J. Taylor, Ana M. Geer, Cameron D. Huke, Katherine E. Wood, Will Tovey, William Lewis, Stephen P. Argent, Andrew M. Teale, Jonathan McMaster, Deborah L. Kays

Summary: The effects of para-substitution on the structural and electronic properties of two-coordinate m-terphenyl Group 12 complexes have been investigated. X-ray crystallography shows little structural variation, but considerable electronic differences are revealed by heteronuclear NMR spectroscopy. Density functional theory calculations are used to rationalize these trends.

Metal-Organic Framework Materials for Production and Distribution of Ammonia

Xue Han, Sihai Yang, Martin Schroder

Summary: Efficient production of ammonia from dinitrogen and water using renewable energy is crucial for the ammonia economy. Functional metal-organic framework (MOF) catalysts have unique properties and show promise in the reduction of N-2 to NH3. By understanding their structure and spectroscopic properties, new advanced catalysts can be developed to produce green NH3. The potential application of MOFs in the capture, storage, and transport of NH3 is also discussed.

Zi Wang, Alena M. Sheveleva, Daniel Lee, Yinlin Chen, Dinu Iuga, W. Trent Franks, Yujie Ma, Jiangnan Li, Lei Li, Yongqiang Cheng, Luke L. Daemen, Sarah J. Days, Anibal J. Ramirez-Cuesta, Bing Han, Alexander S. Eggeman, Eric J. L. McInnes, Floriana Tuna, Sihai Yang, Martin Schroder

Summary: We have investigated the reactivity modulation of nitrogen dioxide (NO2) by a charged metal-organic framework (MOF) material, MFM-305-CH3. Methylated unbound N-centres and Cl- ions in the pores are used to balance the cationic charge. The uptake of NO2 into MFM-305-CH3 leads to the reaction between NO2 and Cl- to form nitrosyl chloride (NOCl) and NO3- anions. The study provides insights into the binding domains and reactivity of adsorbed NO2 molecules within MFM-305-CH3 and MFM-305.

Summary: This paper reports the high adsorption of benzene at low pressure and efficient separation of benzene/cyclohexane achieved by controlling the pore chemistry of two families of robust metal-organic frameworks, UiO-66 and MFM-300. UiO-66-CuII exhibits exceptional adsorption of benzene at 3.92 mmol g-1 and MFM-300(Sc) shows a high selectivity of 166 for the separation of benzene/cyclohexane (v/v = 1/1) mixture. The binding mechanisms of benzene and cyclohexane in these materials are revealed through in situ synchrotron X-ray diffraction, neutron powder diffraction, and multiple spectroscopic techniques. Reversible binding of benzene at an open Cu(II) site within metal-organic frameworks is also visualized for the first time.

Impact of Host-Guest Interactions on the Dielectric Properties of MFM-300 Materials

Xi Chen, Sergei Sapchenko, Wanpeng Lu, Ming Li, Meng He, Yinlin Chen, Mark D. Frogley, Ivan da Silva, Sihai Yang, Martin Schroder

Summary: Metal-organic framework (MOF) materials have gained increasing interest in electronics due to their diverse structures, intrinsic porosity, and designable host-guest interactions. In this study, we investigated the dielectric properties of a series of robust materials, MFM-300(M) (M = Al, Sc, Cr, Fe, Ga, In), upon exposure to different guest molecules. We found that MFM-300(Fe) showed the highest increase in dielectric constant when adsorbing NH3, indicating its potential as a powerful dielectric-based sensor for NH3. Structural analysis and spectroscopy confirmed the electron delocalization induced by host-guest interactions between NH3 and the MOF host, resulting in structural polarization and a high dielectric constant.

Reductive cyclodimerization of chalcones: exploring the self-adaptability of galvanostatic electrosynthesis

Mauro Garbini, Andrea Brunetti, Riccardo Pedrazzani, Magda Monari, Massimo Marcaccio, Giulio Bertuzzi, Marco Bandini

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
