Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ni3(HITP)2 thin-film sensors behave as highly sensitive room-temperature dosimetric H2S sensors because response is not fully recovered after gas removal and increases cumulatively over cycles.
Caveat: Irreversibility is useful for dosimetry but limits reusable reversible sensing.
7 · 2.3 Sensing Characterizations · Figure 4g · Linked to 3 structured results
MASS-PRC enables high-throughput, large-area, ultrathin Ni3(HITP)2 films with controlled thickness, low roughness, high transparency and high conductivity.
Caveat: Sheet-resistance-versus-speed values are graphical estimates; the headline conductivity and transmittance are text-reported.
8 · 3 Conclusions · Linked to 5 structured results
The oriented, small-crystallite Ni3(HITP)2 thin film exposes accessible planar Ni-HITP complexes and 1D pores, increasing H2S reaction sites and response relative to bulk powder.
Caveat: Mechanistic assignment relies on ex situ XPS/EPR and comparative morphology rather than direct in situ gas-surface measurements.
6 · 2.3 Sensing Characterizations · Figure 4b-d · Linked to 7 structured results
The MASS-PRC platform is presented as extensible beyond bare Ni3(HITP)2, including Co3(HITP)2 thin films and Pt-atom immobilisation within Ni3(HITP)2.
Caveat: Co3(HITP)2 and Ni3(HITP)2@Pt are demonstrated structurally, but their transport and sensing data are not reported in the supplied text.
5 · 2.2 Characterizations of Ni3(HITP)2 Thin Film · Figures S10 and S21 · Linked to 2 structured results
H2S sensing involves sulfite formation by Ni-node oxidation chemistry and oxidation of HITP linkers, reducing p-d orbital overlap and increasing resistance.
Caveat: The SI presents this as a proposed mechanism inferred from ex situ spectroscopy and an analogous Ni-HHTP control.
