“…We are interested in the development of catalytic MOFs, in which the metal nodes can act as the catalytic sites and promote the reactions leading to the formation of valuable products. − We found that the Cu I ion is an adequate metal candidate, which prefers to generate coordination hosts with low coordination numbers (usually from 2- to 3-coordination), while allowing additional metal–guest interactions due to its flexible coordination environment (up to 5). − Its potential redox activity is essential for a variety of catalytic reactions. Therefore, construction of porous CuI–MOFs may provide a convenient approach to heterogeneously self-support catalysts with Cu I ions acting as both metal nodes and catalytic sites.…”

The robustly porous metal-organic framework MOF-Cu2I2(BTTP4) (BTTP4 = benzene-1,3,5-triyl triisonicotinate) was shown to work as an efficiently heterogeneous catalyst for the three-component coupling of sulfonyl azides, alkynes, and amines, leading to the formation of N-sulfonyl amidines in good yields. MOF-Cu2I2(BTTP4) can be recycled by simple filtration and reused at least four times without any loss in yield. Studies of the ligand effects on the three-component coupling reactions showed that BTTP4 could enhance the rate, as well as the chemoselectivity, when aromatic alkynes were employed. The catalytic process has been thoroughly studied by means of single-crystal and powder X-ray diffraction, gas and solvent adsorption, in situ (1)H NMR and FT-IR spectroscopy, X-ray photoelectron spectra (XPS), and ICP analysis of Cu leaching.

Comparison of Sensitivity and Low-Frequency Noise Contributions in Giant-Magnetoresistive and Tunneling-Magnetoresistive Spin-Valve Sensors with a Vortex-State Free Layer

et al. 2018

View full text Add to dashboard Cite

Magnetoresistive spin valve sensors based on the giant-(GMR) and tunnelling-(TMR) magnetoresisitve effect with a flux-closed vortex state free layer design are compared by means of sensitivity and low frequency noise. The vortex state free layer enables high saturation fields with negligible hysteresis, making it attractive for applications with a high dynamic range. The measured GMR devices comprise lower pink noise and better linearity in resistance but are less sensitive to external magnetic fields than TMR sensors. The results show a comparable detectivity at low frequencies and a better performance of the TMR minimum detectable field at frequencies in the white noise limit.
