Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Cu3(HHTP)2 can act as an ISM-free solid-contact ion-selective electrode material for Cu2+ sensing, combining ion-to-electron transduction and ion recognition roles.
Caveat: LOD is worse than the conventional Cu3(HHTP)2/ISM comparator, although response is faster.
p001 · Abstract · Linked to 3 structured results
The ISM-free Cu3(HHTP)2 electrode works after ca. 15 min conditioning whereas the Cu3(HHTP)2/ISM electrode nearly loses response under the same short-conditioning protocol.
Caveat: Comparison is for the electrode architecture and conditioning protocol used here.
p005 · 3.5 ISM-free Cu3(HHTP)2 with short conditioning · Fig. 5 · Linked to 3 structured results
The ISM-free Cu3(HHTP)2 electrode retains Cu2+ sensing after organic-solvent exposure better than the Cu3(HHTP)2/ISM comparator.
Caveat: Solvent tests are application-specific electrode tests, not intrinsic framework stability measurements.
p005 · 3.4 Organic solvent resistance · Fig. 4; Figure S5 · Linked to 5 structured results
The ISM-free Cu3(HHTP)2 electrode has weaker selectivity than the Cu3(HHTP)2/ISM comparator, possibly because large MOF pores and weak ion-ligand binding allow interfering-ion exchange.
Caveat: The pore-size explanation is partly inferred and cites prior work for the approximately 20 Angstrom pore size.
p004-p005 · 3.3 Anti-interference capability · Fig. 3a; Tables S4-S5 · Linked to 4 structured results
The authors attribute ion-to-electron transduction primarily to reversible Cu2+/Cu1+ metal-centre redox activity in the Cu3(HHTP)2 MOF.
Caveat: Mechanism is inferred from CV peak assignments; no direct microscopic charge-transport measurement is reported.
