Organic synthesis of hfac
WitrynaMn(hfac)2 complexes of [2-(5-pyrimidinyl)-4,4,5,5-tetramethyl-4,5-dihydro-1H- imidazoline-1-oxyl 3-oxide] (1) and its 2-(3-pyridyl) analogue (2) were prepared. Both complexes formed similar dimer structures. However, their packing patterns were considerably different. The pyrimidine dimers were aligned to form a linear chain … WitrynaTwo complementary design strategies, isomorphous ligand replacement and heterocycle doping, have been applied to iteratively enhance the proton conductivity of a metal–organic framework, β-PCMOF2. The resulting materials, PCMOF2¹/₂(Pz) and PCMOF2¹/₂(Tz) (Pz = 1H-pyrazole, Tz = 1H-1,2,4-triazole), have their proton …
