Solvent triggering structural changes for two terbium-based metal–organic frameworks and their photoluminescence sensing†
Abstract
Two terbium-based metal–organic frameworks (TbPDBA-8 and TbPDBA-9) based on the same ligand have been successfully obtained. Only by changing the solvent content, TbPDBA-9 can be transformed into TbPDBA-8, and the addition of sodium formate will accelerate the process. They showed the detection performance of ascorbic acid and H2O content respectively.
