- Abstract
- Bismuth organic frameworks can display interesting phosphorescent properties, but the relationship between structure and optical activity remains underexplored. Here two bismuth organic frameworks with differing bismuth coordination number and intermetallic distance are contrasted.
Bismuth-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.
