Site-selective bromination of anthracene–maleimide Diels–Alder crystals for tunable afterglow and white light emission

Key Points

• The research focuses on modifying the emission properties of anthracene–maleimide adducts through site-selective bromination.
• Synthesized anthracene–maleimide adducts
• Conducted site-selective bromination
• Assessed phosphorescence and emission characteristics
• Tunable persistent phosphorescence was achieved based on excitation conditions
• White-light emission occurred from the modified compounds
