Deep Eutectic Solvents (DESs) and Their Application

Synthesis and crystal structures of bromo- and ester-functionalised polyhedral silsesquioxanes

Radical initiated hydrobromination and methoxycarbonylation using a Pd(0) complex have been used to convert octavinylsilsesquioxane to species functionalised with alkyl bromide and linear methyl propanoate groups on all eight reactive sites, respectively. The two new molecules, 1,3,5,7,9,11,13,15-octakis[ethylbromide]octasiloxane and 1,3,5,7,9,11,13,15-octakis[methylpropanoate]octasiloxane, have been characterised using NMR (H-1, C-13 and Si-29) and IR spectroscopy, elemental analysis and single crystal X-ray diffraction.

An ionothermally prepared S=1/2 vanadium oxyfluoride kagome lattice

Frustrated magnetic lattices offer the possibility of many exotic ground states that are of great fundamental importance. Of particular significance is the hunt for frustrated spin-1/2 networks as candidates for quantum spin liquids, which would have exciting and unusual magnetic properties at low temperatures. The few reported candidate materials have all been based on d9 ions. Here, we report the ionothermal synthesis of [NH4]2[C7H14N][V7O6F18], an inorganic-organic hybrid solid that contains a S = 1/2 kagome network of d1 V4+ ions. The compound exhibits a high degree of magnetic frustration, with significant antiferromagnetic interactions but no long-range magnetic order or spin-freezing above 2 K, and appears to be an excellent candidate for realizing a quantum spin liquid ground state in a spin-1/2 kagome network.PreprintPostprintPeer reviewe
