Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Cu3(HITP)2 reaches the best reported reflection loss in this paper, RLmin = -63.03 dB, and can cover 3-18 GHz by thickness tuning.
Caveat: The EMW absorber sample is a 60 wt.% MOF/paraffin composite, not a neat framework pellet.
7-8 · Section 2.3 and Conclusion · Figure 5a-b · Linked to 3 structured results
All three prepared c-MOFs form periodic Cu-X4 square-planar coordination units within isoreticular hcb 2D frameworks, with X = N, O or S.
Caveat: CIFs were not supplied; extraction relies on article/SI text, rendered SI tables and figures.
2-4 · Section 2.1 · Figure 1a; Figures S5, S11 · Linked to 5 structured results
Ligand-side Cu-X tuning is proposed to modulate charge distribution and polarity while preserving the framework topology better than changing metal-node connectivity.
Caveat: This is a mechanistic interpretation from the authors; no external comparison experiment was performed within this extraction.
8 · Section 2.3 · Figure 5d · Linked to 5 structured results
Conduction loss is reported as the predominant EMW loss mechanism in the Cu-X4 c-MOFs, with Cu3(HITP)2 having the strongest conduction and polarization losses.
Caveat: Loss-component magnitudes are extracted from figure labels and nonlinear fitting description rather than a table.
7 · Section 2.3 · Figure 4f · Linked to 3 structured results
Cu3(HITP)2 shows the strongest charge-transport performance among the trio because Cu-N coordination promotes d-pi conjugation and both intra- and interlayer charge transport.
Caveat: Carrier mobility is calculated; experimental conductivity is on pressed discs.
