Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Both MOFs detect chromate, dichromate, and permanganate at ppb levels and retain useful quenching after at least three cycles.
Caveat: Detailed Stern-Volmer plots, recyclability plots, and selectivity tests are in the supplied SI.

Both MOFs selectively detect Tl3+ and Hg2+ by fluorescence quenching, with compound I more sensitive than compound II and Tl3+ detected more readily than Hg2+.
Caveat: Full Stern-Volmer plots and detection-limit table are in the supplied SI.
p006 / article p.1158 · Metal-Ion Sensing · Figure 6 · Linked to 8 structured results
No porosity/BET adsorption or electrochemical performance measurements are reported in the supplied main article or Supporting Information text layer.
Caveat: The paper discusses sensing in solution and mentions sorption generally, but no surface area, pore-size, gas adsorption, CV, GCD, EIS, or electrochemical result table was found in the main or SI text layers.

Compound I is a 3D crystalline Mn MOF in monoclinic P21/c.
Caveat: CIF was not supplied locally, so extraction relies on main-text Table 1 and structure description.
p002 / article p.1154 · Structure of [Mn4(C20H10N2O4S)2(HCOO)4(DEF)2] (I) · Figure 1 · Linked to 4 structured results
Compound II is a 2D crystalline Pb MOF in monoclinic P21/n.
Caveat: CIF was not supplied locally, so extraction relies on main-text Table 1 and structure description.
p003 / article p.1155 · Structure of [Pb(C20H10N2O4S)(DMF)] (II) · Figure 2 · Linked to 4 structured results
Compound I shows predominantly antiferromagnetic behaviour, with possible low-temperature ferromagnetic exchanges below 10 K.
Caveat: Low-temperature M-H supporting loops are shown in SI Figure S12.
p004 / article p.1156 · Magnetic Studies · Figure 3; Figures S10-S12 referenced · Linked to 3 structured results
Raman shifts of the N-S vibration after Tl3+ and Hg2+ adsorption support interaction of soft metal ions with the ligand sulfur/N-S functionality.
Caveat: Mechanistic assignment is inferred from Raman peak shifts; no independent binding-site quantification is provided in the main text.
p006 / article p.1158 · Metal-Ion Sensing · Figure 7 · Linked to 6 structured results
Compounds I and II show semiconducting behaviour, attributed by the authors to thermally generated carriers with variable-range hopping.
Caveat: The main text says conductivity increases with decreasing temperature, which is atypical for the stated semiconducting interpretation; SI Figure S13 shows the detailed temperature-dependent conductivity traces.
