Structure-Function Correlation in Switchable DTE@MOF Hybrids: Tracking Local Dynamics and Fatigue Pathways.

ABSTRACT: The origin of optical properties of non-covalently inserted photoswitchable molecules inside porous metal-organic frameworks (MOFs) remains a challenge due to the high mobility and spatial freedom of the embedded dye. Both before and after switching, dye-MOF interaction motifs are subject to changes, which might significantly impact the resulting photochromic response with respect to fatigue resistance. Within this work, the light-induced isomerization processes of a P-type chromophore (dithienylethene) inside the robust UiO-67 are studied with respect to structural rearrangements. For the first time, solid-state NMR (ssNMR) data were utilized next to X-ray diffraction experiments to characterize the embedment and physical state of the photoswitchable dye by tracing changes in both the MOF
