Summary: In this paper, a novel cathode material, quinone functionalized hexahydroxytriphenylene (HHTP) and diphenylbutadiynebis (boronic acid) (DPB) based porous polymer (QHHTP-DPB), is suggested for magnesium-ion batteries (MIBs). The material exhibits a stable and highly porous structure with strong affinities for magnesium ions. Theoretical calculations indicate that the polymer can achieve a high theoretical capacity of 720.48 mAh/g and a positive low open-circuit voltage of 0.39 V. The results suggest that the designed quinone functionalized HHTP-DPB porous polymer could be a potential cathode material for MIBs.
