Advanced microwave absorbing materials(MAMs)are urgently required to eliminate and attenuate microwaves to address the ubiq-uitous microwave radiations and interference.In this contribution,we report the microwave absorption application of a two-dimen-sional(2D)semiconductive metal-organic framework(MOF),i.e.,CuHT(HT=4-hydroxythiophenol),without any pyrolysis at high temperature.Owing to the suitable electrical conductivity(2.69×10-4 S-cm-1),CuHT renders remarkable microwave absorption per-formance,with the minimum reflection loss(RLmin)of-50.9 dB and the effective absorption bandwidth of 4.2 GHz(7.7-10.9 GHz)at a thickness of 1.74 mm.Based on DFT calculation,microwave attenuation is mainly originated from resistance loss due to the con-ducting planes of honeycomb-like Cu2S layers.Thanks to the facile kilogram-scale synthesis,CuHT holds great potential for future mi-crowave absorption applications.
