Structurally Diverse Triphenylamine[<i>n</i>]arenes with Room-Temperature Phosphorescence
We present the design and synthesis of a series of triphenylamine[<i>n</i>]arenes. The incorporation of alkyl and aryl aldehydes together with paraformaldehyde introduces multiple reactive sites into the macrocyclic framework. The methylenes can be oxidized to carbonyls using 3,5-dichloro-2,6-dicyano-1,4-benzoquinone (DDQ), which exhibits significantly enhanced fluorescence and room-temperature phosphorescence (RTP). This investigation provides an efficient strategy for the synthesis of RTP-active macrocyclic arenes, thereby broadening the scope of macrocyclic arene chemistry and advancing their application in luminescent materials.
