Transient absorption spectroscopy and photochemical reactivity of CAU-8

[EN] CAU-8 is a metal organic framework with the composition [Al(OH)(BPDC)] (BPDC: 4,4'-benzophenone dicarboxylate) whose structure is constituted by chains of corner-sharing AlO6 octahedra connected by BPDC linkers, giving rise to an array of non-intersecting channels. According to the wel...
