Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
IC-CuTHPP selectively distinguishes cadaverine from common VOCs because cadaverine gives an irreversible response whereas VOC responses recover.
Caveat: VOC response magnitudes for individual VOCs are approximate figure reads.

IC-CuTHPP detects trace cadaverine down to 20 nL experimentally, with a calculated LOD of 4.9 nL and response time around 13.5 s.
Caveat: The 4.9 nL LOD is explicitly a rough estimate, not a measured response at 4.9 nL.

Five structurally analogous ionically conductive MTHPP MOF thin films were prepared using Cu2+, Ni2+, Zn2+, Co2+ and Mg2+.
Caveat: Detailed XRD/FT-IR numerical evidence is shown primarily for CuTHPP; other metals are presented as an analogous series and by SI structures/sensing curves.

Among the five MTHPP IC-MOF sensors, IC-CuTHPP gives the strongest cadaverine response.
Caveat: Non-Cu values are read approximately from figures; Cu values are explicitly reported in text.

The irreversible cadaverine response is attributed to strong coordination/complexation between cadaverine and Cu2+ remaining in the CuTHPP IC-MOF film.
Caveat: Authors state this as a mechanism supported by XPS and XRD; direct complex structural identification is not reported.

Mobile Cu2+ ions in IC-CuTHPP are responsible for the ionic conduction signature and play a key role in sensing.
Caveat: The paper provides qualitative current-time evidence rather than extracted ionic conductivity values.
