Glass transition-induced luminescence in ZIF-62

Puntos clave

• Enhanced luminescence occurs in the glassy state of ZIF-62, contrasting with fluorescence quenching in its crystalline form.
• The theoretical simulation revealed configurations in ZIF-62's glassy state that lead to intensified luminescence, supported by experimental data.
• Combining ab initio molecular dynamics with quantum mechanical calculations provided insights into luminescent behaviors.
• These findings highlight the importance of the glass transition in tuning luminescence properties of coordination polymers.
