  摘要：

  Triamino-s-triazine derivatives 3a, 4, and 5 have been prepared, and their cationic states have been analyzed electrochemically. At 298 K, 3a(+) has a limited lifetime in CH2CI2 solution, However, 4(+) and 5(+) are long lived under such conditions, and quartet states of 4(3+) and 5(3+) are observed by ESR spectroscopy, Variable temperature ESR analysis and NMR shift susceptibility measurements indicate that 5(3+) is a doublet ground state with a populated quartet state.

  AbstractOrganic LPL (long‐persistent luminescence) materials have sparked extensive research interest due to the ultralong‐lived triplet states. Although numerous organic LPL materials have been reported, most of the triplet emission was static and monotonous. Therefore, LPL materials with dynamic triplet emission are urgently required. A triamino‐s‐triazine derivative 1 with dynamic LPL was fabricated. The single‐crystal structure shows that the abundant intermolecular interactions and small free volume restrict the molecular motion and avoid the quenchers. Spectral and theoretical calculations upheld the existence of multiple excited states in 1, and the migration of electrons between multiple excited states is very sensitive to external stimuli. By modulating the stimulus, the residence of electrons in different triplet states can be manipulated to achieve RGB LPL. Importantly, blue LPL was achieved by manipulating the anti‐Kasha emission. And the red LPL can still be observed at high temperature.
