Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The 35-couple module reached 750 microW at Delta T 82 K, which the authors state was the highest power then reported for organic-material thermoelectric devices.
Caveat: Historical best-value claim is time-dependent and reflects the authors' publication context.
935 · Device performance · Figure 3d · Linked to 1 structured result
A single n-p thermocouple made from the polymers can produce a 3.5 K temperature difference at 0.6 V, but the full module did not show observable cooling.
Caveat: Full-module cooling was not detected, likely because of module size and heat dissipation.
936 · Refrigeration test · Figure S4 · Linked to 1 structured result
The exact formulae of the polymers are uncertain because the samples are insoluble and amorphous, preventing NMR and X-ray diffraction structure determination.
Caveat: Elemental-analysis data are reproducible but do not yield exact formulae.
933 · Structure discussion · Table 1
poly[Nax(Ni-ett)] contains square-planar, low-spin Ni centres coordinated by sulfur atoms.
Caveat: XANES differs from reference Ni bis-dithiolene complexes in ways the authors state are not yet clear.
934 · XAS/XPS discussion · Figure 1; Figure S1a · Linked to 2 structured results
Replacing bulky tetraalkylammonium counter cations with Na+ or K+ gives much higher conductivity because bulky alkyl groups hinder close packing and inter-chain charge transport.
Caveat: Mechanistic interpretation is based on packing arguments rather than direct crystallographic structure.
934 · Thermoelectric properties · Table 1 · Linked to 4 structured results
poly[Cux(Cu-ett)] has nearly doubled thermal conductivity compared with the two n-type Ni polymers, possibly because of higher metal-ion content.
Caveat: Thermal-conductivity values are graph-read estimates; the mechanism is proposed by the authors.
935 · Temperature-dependent TE properties · Figure 2c · Linked to 3 structured results
Charge transport in the studied polymers follows a three-dimensional variable-range hopping model.
Caveat: Based on graphical linearity of ln(sigma) versus T^(-1/4), with no fitted slope parameters reported.
934 · Transport mechanism · Figure S3 · Linked to 1 structured result
The nickel polymers in Table 1 are n-type, while poly[Nax(Cu-ett)] and poly[Cux(Cu-ett)] are p-type, as indicated by the sign of the Seebeck coefficient.
Caveat: The origin of the nickel/copper carrier-type difference is discussed as unresolved.
