“…The signals at g = 2.004 can be attributed to anion-sulfur vacancy (V S ), and the signals at g = 2.185 can be assigned to cation-cuprum vacancy (V Cu ), which is consistent with the results observed by atomic-resolution STEM. 39,40 In contrast, Cu 9 S 5 and P-MoS 2 exhibit extremely weak EPR signal intensities, demonstrating the presence of a small number of vacancy defects in the individual components as well. The concentrations of V S and V Cu exhibit a synchronous trend with the change in doping elements.…”

Trinitarian designs in the morphology, components, and microstructure remain challenging for advanced electromagnetic wave absorption (EMWA) materials with light weight, strong absorption, and well-defined structure−function relationships. Herein, a series of X-doped MoS 2 /Cu 9 S 5 with multilevel honeycomb structures (X-MoS 2 /Cu 9 S 5 MHs, X = P, Si, Ge) were designed by space-confined growth and in situ sulfidation of a polyoxometalate-based metal−organic framework. X-MoS 2 /Cu 9 S 5 MHs possess low density, high surface area, and abundant cationcuprum and anion-sulfur double vacancies (V Cu and V S ) simultaneously that are unmatched by conventional EMWA materials. Also, the systematic investigation of the doping effect of various polyoxometalate heteroatoms on V Cu and V S in the microhoneycomb has been conducted. Experimental results and density functional theory calculations reveal that the excellent EMWA performance (−56.21 dB) results from the synergistic effect of morphology design, component optimization, and vacancy regulation. This study not only provides an important opportunity to understand a morphology-component-microstructure strategy in electromagnetic wave absorption but also builds a noteworthy bridge between bioinspired engineering and microscale absorbers.

Graphdiyne (GDY), a rising star of carbon allotropes, features a two-dimensional all-carbon network with the cohybridization of sp and sp 2 carbon atoms and represents a trend and research direction in the development of carbon materials. The sp/sp 2 -hybridized structure of GDY endows it with numerous advantages and advancements in controlled growth, assembly, and performance tuning, and many studies have shown that GDY has been a key material for innovation and development in the fields of catalysis, energy, photoelectric conversion, mode conversion and transformation of electronic devices, detectors, life sciences, etc. In the past ten years, the fundamental scientific issues related to GDY have been understood, showing differences from traditional carbon materials in controlled growth, chemical and physical properties and mechanisms, and attracting extensive attention from many scientists. GDY has gradually developed into one of the frontiers of chemistry and materials science, and has entered the rapid development period, producing large numbers of fundamental and applied research achievements in the fundamental and applied research of carbon materials. For the exploration of frontier scientific concepts and phenomena in carbon science research, there is great potential to promote progress in the fields of energy, catalysis, intelligent information, optoelectronics, and life sciences. In this review, the growth, self-assembly method, aggregation structure, chemical modification, and doping of GDY are shown, and the theoretical calculation and simulation and fundamental properties of GDY are also fully introduced. In particular, the applications of GDY and its formed aggregates in catalysis, energy storage, photoelectronic, biomedicine, environmental science, life science, detectors, and material separation are introduced.
