Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
I2-incorporated EuL is presented as an iodine-element-incorporated MOF usable for conductivity studies under anhydrous conditions and moderate temperature.
Caveat: Conductivity is modest; authors stopped measurements above 80 degC because TGA showed significant iodine loss.

Activated EuL has permanent porosity with type-I N2 sorption behaviour.
Caveat: Surface area and pore volume are modest and lower than a previous Yb analogue discussed by the authors.
239 · General characterization · Fig. S4 · Linked to 3 structured results
Cu2+ sensing sites are located inside EuL channels rather than only on the crystal surface.
Caveat: EDS line-scan evidence is qualitative and figure-based.
240 · Luminescence properties · Fig. 5 · Linked to 2 structured results
The delayed iodine loss in I2-incorporated EuL suggests interaction between iodine and the framework.
Caveat: Interaction is inferred from TGA hysteresis rather than directly resolved iodine positions.
239 · General characterization · Fig. 2; Fig. S3 · Linked to 2 structured results
Acetone quenches EuL luminescence because the BPT absorption band overlaps the acetone absorption band, reducing energy transfer to Eu3+.
Caveat: Mechanism is proposed from spectral overlap and luminescence response, not from time-resolved mechanistic proof.
240 · Luminescence properties · Fig. 6 · Linked to 3 structured results
The authors speculate that iodide/polyiodide species confined in EuL channels act as the charge-carrier medium.
Caveat: Carrier identity is described as speculation by analogy to prior iodine-loaded MOFs; no direct speciation data are reported here.
