a Images of the phosphorescences of the films with different proportions of three-component polymer under 365 nm excitation at room temperature. xyz represents the PY-AMI: ABM-2AMI: PHE-2AMI ratio. b Schematic diagram and local molecular formula of the three-component afterglow-tunable polymer TPAP. The red regular hexagon represents the central group of PY-AMI, the blue represents PHE-2AMI and the green represents ABM-2AMI. c Phosphorescence spectra of three-component polymers with different PY-AMI: ABM-2AMI: PHE-2AMI ratios under 365 nm excitation and environmental conditions. d Phosphorescence lifetimes of the three-component polymers with different PY-AMI: ABM-2AMI: PHE-2AMI ratios at 500 nm and 610 nm under environmental conditions (λex = 365 nm). “118” represents TPAP-118. e CIE coordinate diagram corresponding to the phosphorescence spectra of the three-component polymers.
