a Steady-state photoluminescence spectra of the TPAP-514 film excited at 365 nm. b Two-dimensional excitation–emission spectra of TPAP-514 film (excitation wavelength from 200 to 400 nm, emission wavelength from 400 to 750 nm). c The phosphorescence decay curves of 512 nm emission band of TPAP-514 film under 365 nm excitation in the temperature range of 80–280 K. d Temperature-dependent phosphorescence spectra of TPAP-514 films from 80 to 280 K (λex = 365 nm). e Time-resolved phosphorescence emission spectra of PAABM, PAPHE, PAPY, TPAP-514 at room temperature under 365 nm excitation. f Absorption and emission spectra of three kinds of one-component polymer films at room temperature. g Excitation spectra of TPAP-514 film obtained at 512 and 610 nm under room temperature, respectively. h Emission spectra of prompt and delayed phosphorescence of TPAP-514 at different delay times (td = 2–100 ms).
