Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
CuPc-MCOF-coated fibres provide low-ng L-1 chlorophenol detection by EE-SPME-GC-MS/MS with good reproducibility and real-sample recoveries.
Caveat: Application performance is for a composite coated fibre, not a standalone powder device.
p.7-p.9 · 3.5. Method validation; 3.6. Analysis of real samples · Table 2; Table 4 · Linked to 5 structured results
The current extraction used both the office SI text and rendered SI surrogate; SI figures are available as images, but most SI figure panels remain qualitative rather than tabulated raw data.
Caveat: Numeric SI-only values were taken only when printed clearly in the rendered pages, such as Fig. S5 and Table S1.
p.1-p.8 · Supplementary materials · Fig. S1-S11; Table S1 · Linked to 1 structured result
CuPc-MCOF was successfully synthesised as a crystalline piperazine-bonded MCOF, supported by new PXRD peaks, FT-IR bond formation and XPS composition.
Caveat: The supplied SI text contains only captions for schematic and additional XPS figures; figure panels were not available locally.
p.3 · 3.1. Synthesis and characterization · Fig. 1 · Linked to 5 structured results
Pore-size matching, hydrophobic/fluorinated surface character, pi-pi stacking, hydrogen bonding, metal coordination and electrostatic changes together support selective CP adsorption on CuPc-MCOF.
Caveat: Mechanistic assignments are supported by characterization and adsorption trends rather than isolated binding constants.
p.8 · 3.7. Extraction mechanism · Fig. S10-S11 · Linked to 5 structured results
CuPc-MCOF retains chemical and thermal stability under the reported acid/base/solvent soaking and thermal-desorption-relevant conditions.
Caveat: Chemical stability evidence is qualitative from unchanged PXRD/FT-IR patterns; no quantitative crystallinity retention is reported.
p.6 · 3.3. Stability of CuPc-MCOF coated fibers · Fig. 4a; Fig. S8-S9 · Linked to 3 structured results
The conductive CuPc-MCOF coating facilitates electron transport and charge-attraction-driven migration during EE-SPME.
Caveat: Conductivity is inferred from CV/EIS behaviour; no absolute electronic conductivity value is reported.
