Abstract
AbstractIt is still difficult to design efficient organic‐based room‐temperature phosphorescence (RTP). Here a facile strategy is reported to tailor efficient RTP by encapsulating trace amount of aromatic‐acid‐based phosphors within crystalline solvento matrices [Al(DMSO)6]X3 (X− = Cl− or Br−, DMSO = dimethyl sulfoxide, (CH3)2SO) in situ. The resultant single crystal complexes feature bright long‐lasting afterglows with maximum RTP peaks ranging from 430 to 580 nm and the best lifetime up to 1.9 s, as well as the highest yellow RTP quantum yield of 58.3%. The enhanced intersystem crossing and the suppression of nonradiation decay derived from the tight matrices are responsible for the appreciable RTP. White‐light emission is further realized in both prompt state and delayed state. In this case, data encryption and decryption applications are successfully performed by using these complexes. The design and construction strategy embodied here render this approach promising for the exploitation of versatile RTP species for specific applications.
