Key points
- Two MOFs were synthesized using Zn(II) and Cd(II) with 3,8-dibromophenanthroline, leading to distinct coordination and halogen bonding.
- The MOFs exhibit different thermal quenching behaviors: 38.9% for one and 11.9% for the Cd-MOF at 150°C.
- The Cd-MOF's anti-thermal-quenching performance surpasses many reported inorganic phosphors.
- Phosphor-converted LED devices assembled with these MOFs confirm their potential for solid-state lighting.

Abstract
Abstract Diverse coordination geometries of Zn(II) and Cd(II) give rise to distinct halogen bonding interactions and spatial arrangement of the 3,8-dibromophenanthroline luminescent center in two MOFs. The two materials exhibit distinct thermal quenching degrees of 38.9% and 11.9% at 150 °C. The Cd-MOF presents outstanding anti-thermal-quenching performance superior to many reported inorganic phosphors. Assembled phosphor-converted LED devices confirm their great potential for solid-state lighting.
