| Abstract |
In this study, we exchanged [Et2NH2]+ counter-cations in the anionic In-BTB metal-organic framework (MOF), [Et2NH2]3[In3(BTB)4]·10DEF·14H2O, with a series of cationic dyes to prepare dye-encapsulated In-BTB MOFs (dye@In-BTBs). We chose six cationic dyes for the cation exchange: rhodamine 6 G (Rh6G), nile blue A (NBA), Astrazon Orange G (AOG), crystal violet (CV), 3,3′-diethyloxacarbocyaine iodide (DEOCy), and 2-[4-dimethylamino]styryl)-1-methylpyridinium (DMMP). The cationic dyes have different geometries and physical dimensions. Six cationic dyes were easily exchanged with ammonium ions, and we successfully solved the crystal structures of six dye@In-BTBs. The confined spaces of In-BTB only allowed the dyes to contain structures somewhat different from free state. In addition, the distances between each captured dye was also different from the dyes in their solid states. Therefore, these differences led to unique photophysical properties of each dye compared to its free state. Detailed photophysical properties of the captured dye molecules will be presented. |
