a, b UV–vis absorption (dashed lines), normalized SSPL spectra (solid lines), PLQYs (inset) (a), and lifetimes (b) in n-hexane at the concentration of 10-5 M under ambient conditions. c, d Calculated energy levels and wavefunctions for the frontier molecular orbitals of TTM-1Cz (c) and TTM-1CzBr (d). e Calculated molecular conformation variation of D0-D1. f Potential energy curves of D0 and D1 for TTM-1CzBr. Abs.: absorption; Fluo.: fluorescence. g Fluorescence stabilities of TTM-1Cz and TTM-1CzBr in PSF (doping concentration: 5 wt%) under the irradiation of a 376-nm pulsed laser at ambient conditions.
