Abstract

AbstractBismuth-based organic frameworks (BiOFs) can display interesting phosphorescent properties, but the relationship between structure and optical activity remains underexplored. The structure-dependent phosphorescence properties in the BiOFs are investigated using different multidentate ligands. In-depth analysis of the luminescence properties confirms that the densely packed framework shows long-lasting phosphorescence at room temperature, owing to an efficient electron-hole separation. The combination of spectroscopic analysis and single-crystal structural analysis provides important insights into the emission control through BiOFs structural change, which can be a useful strategy for modulating the optical properties of various metal organic frameworks. Furthermore, taking the advantage of long-lasting phosphorescence, the potential usage as an eco-friendly photocatalyst is demonstrated.
