Metal−organic framework (MOF)-derived materials have gained popularity as microwave absorbing materials due to their electromagnetic dissipation advantages. In this study, a special type of MOF (ZIF-L) was used as a precursor; tannic acid was introduced for chemical etching. The resulting material obtained by in situ carbonization was a hollow structure of N-doped carbon embedded by Co nanoparticles (CoHNC), which retained the original pumpkin seed shape but had a hierarchical porous structure on the inside. By adjustment of the amount of cobalt nitrate and the carbonation temperature, the electromagnetic parameters could be altered, improving impedance matching and enabling different microwave absorption properties to be obtained. At 16.96 GHz, the material exhibits an optimal reflection loss of −45.5 dB, an effective bandwidth of 3.04 GHz, and a matching thickness of only 1.4 mm with a material filler of 30 wt %. The microwave loss mechanism is formed by the dual loss mechanism with dielectric loss as the main loss and magnetic loss as the auxiliary one. Therefore, the synthesis of the CoHNC composite through simple etching provides a useful idea for optimizing microwave absorbing materials.

“…MOFs, 38–41 renowned for their intricate and tunable structures, stand out as a versatile canvas for materials design. 42 These frameworks consist of metal ions 43–46 or clusters intricately linked by organic ligands, 47–51 resulting in a crystalline and porous architecture. The metal nodes, 52–56 often forming the backbone of the framework, are strategically connected by organic molecules, giving rise to a highly organized and tunable structure.…”

“…[1] This extraordinary kind of material is constructed by connecting π-conjugated organic building blocks with metal ions to form d-π extended layered structure, offering high surface areas and electrical conductivity. [1b,2] The elegant combination of electrical conductivity and porosity makes them particularly attractive for a wide range of applications, ranging from electrochemical energy storage, [3] electrochemical catalysts, [4] to chemiresistive sensors, [5] and others. [1c,6] Another compelling feature of conductive MOFs lies in their inherent tunability stemming from a wide range of poten-tially accessible organic building blocks with diverse configurations [7] and feasible functionalization of organic fragments, which makes conductive MOFs highly adaptable for various applications.…”

Electrically conducting two‐dimensional (2D) metal‐organic frameworks (MOFs) have garnered significant interest due to their remarkable structural tunability and outstanding electrical properties. However, the design and synthesis of high‐performance materials face challenges due to the limited availability of specific ligands and pore structures. In this study, we have employed a novel highly branched D3h symmetrical planar conjugated ligand, dodechydroxylhexabenzotrinaphthylene (DHHBTN) to fabricate a series of 2D conductive MOFs, named M‐DHHBTN (M = Co, Ni, and Cu). This new family of MOFs offers two distinct types of pores, elevating the structural complexity of 2D conductive MOFs to a more advanced level. The intricate tessellation patterns of the M‐DHHBTN are elucidated through comprehensive analyses involving powder X‐ray diffraction, theoretical simulations, and high‐resolution transmission electron microscope. Optical‐pump terahertz‐probe spectroscopic measurements unveiled carrier mobility in DHHBTN‐based 2D MOFs spanning from 0.69 to 3.10 cm2 V‐1 s‐1. Among M‐DHHBTN famility, Cu‐DHHBTN displayed high electrical conductivity reaching 0.21 S cm−1 at 298 K with thermal activation behavior. This work leverages the “branched conjugation” of the ligand to encode heteroporosity into highly conductive 2D MOFs, underscoring the significant potential of heterogeneous double‐pore structures for future applications.
