AC||1-ox gives high device-level energy and cycling stability for a MOF-based supercapattery.
Caveat: Device includes activated carbon negative electrode and conductive/binder additives; comparison to literature is application-level, not intrinsic MOF transport.

Iodine-treated 1-ox and 1-ox' retain the crystalline TTF-Cu MOF framework, although PXRD peaks broaden and shift due to iodine intercalation.
Caveat: PXRD changes indicate some structural perturbation after iodine treatment.

The higher three-electrode capacity of iodine-treated 1-ox is attributed to enhanced conductivity and densely aligned active sites in the 2D layered structure.
Caveat: Electrode contains Super P conductive carbon and PTFE binder; reported capacity is for composite electrode preparation.

The coordinated CN- in 1 is generated in situ mainly by S-C bond cleavage of SCN-, avoiding use of highly toxic metal cyanides.
Caveat: Mechanistic assignment is based on precursor screening and literature precedent; no direct isotopic tracing is reported.
p002 / 4673 · 2.1. Synthesis and Crystal Structures
The conductivity increase after iodine treatment is mainly attributed to electrical conduction through the oxidised MOF framework and higher TTF radical-cation/free-carrier density, with iodine also contributing.
Caveat: Conductivity was measured on pressed pellets; carrier concentration was inferred spectroscopically rather than directly measured.

Charge/discharge in the 1-ox electrode is organic ligand-centred rather than metal-centred; Cu remains Cu+ while C 1s ratios shift reversibly.
Caveat: Based on ex situ XPS peak assignments after cycling.
