A facile way to construct metal-free phosphorescent amorphous polymers is developed. The resulting materials show strong room-temperature phosphorescence (RTP) luminescence in ambient atmosphere, and phosphorescent quantum yields are achieved at a high level without extra processing. Some potential applications as encryption ink are also studied as the materials are water-responsive and photoresponsive.
