Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
IFMC-69 selectively adsorbs CO2 over N2 and may be useful for CO2/N2 mixture separation.
Caveat: Selectivity is adsorption-based; no dynamic breakthrough separation experiment is reported.

IFMC-69 can reversibly adsorb and release iodine, with accompanying photoluminescence quenching and recovery.
Caveat: Reversibility is demonstrated by colour and luminescence changes; cycle life is not quantified.

Transformation from IFMC-68 to IFMC-69 converts an air-unstable framework to an air-stable one.
Caveat: Stability assessment is PXRD/photo based under ambient air exposure, not a full environmental stability matrix.

DFT calculations support IFMC-69 formation as thermodynamically favourable through formation of the water-bridged [Zn4O(CO2)6]2H2O SBU.
Caveat: Model calculations use simplified SBUs with benzene substituents replaced by H atoms; they support but do not prove the full solid-state pathway.

The IFMC-68 to IFMC-69 SCSC transformation is triggered by reaction temperature and time, in solvent or solvent-free sealed conditions.
Caveat: Intermediate phase is described by PXRD and selected single-crystal evidence but not assigned as a separate solved structure.

Iodine adsorption in IFMC-69 increases conductivity by enabling charge-transfer interactions between I2 and pi-electron walls within narrow channels.
Caveat: Mechanistic explanation is author interpretation; transport evidence is limited to pressed-film resistance/conductivity and an unfitted Nyquist plot.
