Journal of Materials Chemistry A, 2015, 3, pp.3294-3309. ⟨10.1039/C4TA03992K⟩

The functionalization of metal–organic frameworks (MOFs) with free carboxylic groups is naturally difficult due to their potential coordination with metal ions. The impact of functionalizing the archetypical metal organic framework UiO-66(Zr) with

Publikováno v: Journal of the American Chemical Society

The incorporation of Ti ions within the framework of aluminophosphate zeotype AlPO-5 and their chemical reactivity is studied by means of CW-EPR, HYSCORE, and UVvis spectroscopies. Upon reduction, Ti3+ ions are formed, which exhibit large 31P hyperfi
