Description
Summary:A cage-based anionic Na( i )-organic framework with a unique Na 9 cluster-based secondary building unit and a cage-in-cage structure was constructed. The selective separation of dyes with different charges and sizes was investigated. Furthermore, the Rh6G@MOF composite could be applied as a recyclable fluorescent sensor for detecting picric acid (PA) with high sensitivity and selectivity. A unique nanoporous Na( i )-MOF with excellent dye separation performance is presented and the dye@MOF composite could be applied as a luminescent sensor for picric acid detection.
