Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The authors position one-pot M-TCNQ synthesis as a route to conductive microwave absorbers without pyrolysis or calcination of MOF precursors.
Caveat: No numerical yield or life-cycle comparison is reported.
1677-1684 · Introduction / Conclusions · Linked to 3 structured results
The best EAB value is consistently 5.44 GHz for paraffin-based Cu-TCNQ, but the associated thickness is inconsistent between the main-text sentence and SI Table S1/abstract.
Caveat: Use the SI Table S1 value for structured comparison and retain the main-text value separately.

Cu-TCNQ is the only member of the M-TCNQ series with conductivity high enough to fall in the authors' microwave-absorbing-material window, explaining its stronger dielectric loss.
Caveat: Conductivity was derived by LSV; test geometry is not fully described.
1681-1684 · 3.1 / 3.2 · Figure 3e; Figure 5a · Linked to 4 structured results
Fe-TCNQ and Ni-TCNQ show poor microwave absorption because their low conductivity restricts charge-carrier mobility and conduction loss.
Caveat: Fe-TCNQ structural assignment is less secure than Cu/Ni by XRD.
1683-1684 · 3.2 · Figure 4h,i · Linked to 4 structured results
The hierarchical pore structures are proposed to promote multiple reflection and scattering of incident electromagnetic waves.
Caveat: Porosity is measured, but the scattering contribution is inferred rather than isolated experimentally.
1681 · 3.1 · Figure S5 · Linked to 6 structured results
The coexistence of conductive phase I and less-conductive phase II in Cu-TCNQ may improve absorption by creating heterogeneous interfaces that enhance interfacial polarisation.
Caveat: Phase fractions are not quantified.
1681 · 3.1 · Figure 2f · Linked to 2 structured results
DFT supports Cu-N chains as an efficient charge-transport path in Cu-TCNQ, with a calculated 2.34 eV bandgap and charge migration toward the benzoquinone ring.
Caveat: The CIF was not supplied with the extraction package; model verification is deferred.
1684 · 3.2 · Figure 5b,d,e · Linked to 2 structured results
Cu-TCNQ attenuation is attributed to multiple reflection, interfacial polarisation, and conduction/resistance loss along Cu-N chains.
Caveat: Mechanistic attribution combines experimental dielectric analysis and DFT, not a direct microscopic transport measurement.
