Cu3HHTT2-1 sensors deliver state-of-the-art room-temperature responses to NH3 and NO2 with selectivity over H2S, ethanol, methanol, acetone, benzene, and toluene.
Caveat: Benchmark comparisons depend on response definitions and literature conditions; response sign differs between NH3 and NO2 regimes.
p007 / article p.20219 · Conclusions · Figures 5d, 6d, Tables S3, S4 · Linked to 4 structured results
Cu3HHTT2 humidity response is divided into dry, water adsorption, and water condensation regimes, with a threshold around 25% RH.
Caveat: The exact boundary is approximate and condition-dependent.

The strong humidity-dependent resistance fluctuation is unique to Cu3HHTT2 compared with triphenylene-based control cMOFs.
Caveat: Control comparison is mainly presented graphically and qualitatively in Figure 2.

Water enables proton percolation/transport in Cu3HHTT2, turning the electrically conductive framework into a dual ionic-electronic conductor.
Caveat: EIS conductivities are low and measured on pressed coin cells; device resistance also includes electronic contribution.
p001 / article p.20213 · Abstract · Linked to 4 structured results
NH3 enhances the low-humidity response by helping form hydrogen-bonded interconnections between adsorbed water molecules, increasing proton conduction and decreasing resistance.
Caveat: Mechanistic assignment is inferred from humidity-dependent resistance and known hydrogen-bonding behaviour rather than direct proton-tracking measurement.
p004 / article p.20216 · NH3 Sensing · Figure 4, Figure 5 · Linked to 2 structured results
NO2 reacts with water and disrupts the humid hydrogen-bond network, hindering proton conduction and increasing resistance at high RH.
Caveat: The reaction products are supported by ex situ XPS; dynamic in situ speciation was not reported.
