Abstract: strong hydrogen bonding and π-conjugation effects. Covalent bonding in MAMP and MAEP compounds provides greater rigidity and exciton stability than hydrogen-bonded systems, resulting in prolonged afterglow durations, while Br-bonding enhances ISC and spin-orbit coupling (SOC), and the weak interactions increase non-radiative decay, further reducing afterglow duration. Density functional theory calculations confirm the enhanced SOC in MAMP and MAEP compounds, further improving RTP efficiency. This work demonstrates the precise control of RTP properties, highlighting the potential in advanced anti-counterfeiting and emerging photonics applications.
