Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The dynamically controlled air-liquid interface synthesis yields record electrical conductivity of 100-200 S cm-1 in Ni-N 2D cCP films and power factors up to 10 uW m-1 K-2 among reported 2D cCP thermoelectrics.
Caveat: Conductivity may be underestimated due to powder contaminants underneath films and occasional micro-cracks.
p008 · Conclusion · Linked to 3 structured results
Reported conductivities may be underestimated because powder contaminants occur underneath the films and occasional micro-cracks are present.
p003 · Synthesis and Characterizations · Figures S10-S12 · Linked to 2 structured results
The films produced by the method are poorly crystalline layered 2D cCPs with broad XRD/GIWAXS pi-pi stacking signatures rather than long-range crystalline frameworks.
Caveat: Chemical bonding is supported by FTIR/Raman, but long-range structural order is weak.
p004 · Synthesis and Characterizations · Figure S14 · Linked to 1 structured result
Host-guest interactions with ambient O2/H2O substantially modulate conductivity and Seebeck sign, including carrier-type switching in Ni-HAB and Ni-HATI-H after degassing.
Caveat: Individual Figure 2 bar values are approximate where not text-reported.
p005 · Host-Guest Interaction-Modulated Thermoelectrics · Figure 2 · Linked to 4 structured results
DFT indicates O2 interactions are stronger than H2O interactions in Ni-HAB/Ni-HATP, and the Ni-HAB O2-linker complex is especially favourable with large charge transfer.
Caveat: DFT uses molecular model systems rather than periodic film structures.
p006 · Host-Guest Interaction-Modulated Thermoelectrics · Figure 3; Tables S2-S4 · Linked to 3 structured results
High-conductivity films require coordination competition from Ni(acac)2, N2 setup followed by slow air diffusion through a non-airtight cap, and NH4OH rather than NaOAc as base.
Caveat: Detailed optimisation was most extensive for Ni-HAB; HATI linker syntheses were external/literature.
p003 · Synthesis · Linked to 3 structured results
Ni-HATP transport is grain-boundary-limited and best described by heterogeneous transport through small ordered domains linked by grain boundaries supporting disordered metallic transport plus hopping contributions.
Caveat: Model parameters are fitted; the exact microstructural partitioning is inferred from diffraction/morphology and transport behaviour.
