Thermally activated delayed fluorescence (TADF) has been explored actively in luminescent organic materials. Yet, realizing such TADF-active, multifunctional emitters with high emission efficiency still remains hugely challenging. In this context, a series of twist-conjugated organic mols. bearing diphenylsulfone and 9,9-dimethylacridine moieties are designed and prepared, and are found to show, in one mol., TADF, room-temperature phosphorescence, triboluminescence, and aggregation-induced emission enhancement. In addition, remarkably high photoluminescence quantum efficiency, up to 閳?00%, is achieved for these novel mols. Single-crystal anal. and theor. calculations reveal that the through-space charge transfer (TSCT) effect in these mols. is responsible for both the multifunctional emission and high emission efficiency. A maximum external quantum efficiency of 20.1% is achieved, which is among the highest recorded in a solution-processable device containing TSCT-based TADF materials. These results illustrate a new approach to achieving highly efficient TADF-active, multifunctional emitters. In the experiment, the researchers used many compounds, for example, 1,2-Difluoro-3-iodobenzene (cas: 64248-57-3COA of Formula: C6H3F2I).
1,2-Difluoro-3-iodobenzene (cas: 64248-57-3) belongs to iodide derivatives. Organoiodine compounds occur widely in organic chemistry, but are relatively rare in nature. Organoiodine lubricants can be used with titanium, stainless steels, and other metals which tend to seize up with conventional lubricants: organoiodine lubricants can be used in turbines and spacecraft, and as a cutting oil in machining.COA of Formula: C6H3F2I
