Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Electrochemical redox-state control switches Zn(pyrazol-NDI) between insulating and semiconducting conductivity regimes over 100 cycles.
Caveat: Switching was demonstrated in an electrochemical thin-film measurement rather than in a standalone electronic device.
4-5 · Redox state dependent conductivity · Fig. 3d · Linked to 4 structured results
The reported activation energies should not be over-interpreted because the ideal theory assumes purely electronic self-exchange, while measured redox conduction involves ion-pairing, intermolecular interactions and non-unity activity effects.
Caveat: Caveat is explicitly stated by the authors.
4,6 · Redox state dependent conductivity · Fig. 3c · Linked to 4 structured results
The redox conductivity is coupled to countercation motion; Li+ and TBA+ lower the 0.5-Zn(pyrazol-NDI) maximum conductivity and increase the activation barrier relative to K+.
Caveat: Authors discuss non-ideal ion-pairing and size effects; exact mechanistic partitioning is not directly quantified.
7 · Counter cation dependent redox conductivity · Fig. 5 · Linked to 6 structured results
Zn(pyrazol-NDI) shows bell-shaped redox conductivity that peaks at mixed redox states x = 0.5 and x = 1.5 and collapses for the neutral or fully reduced states.
Caveat: Exact curve points require the source data file; extracted peak at x = 1.5 is estimated from the figure.
4 · Redox state dependent conductivity · Fig. 3b · Linked to 5 structured results
The bell-shaped redox-conductivity signature is reproduced in Zr(dcphOH-NDI) and UU-100(Co), indicating generality across different SBUs and redox-active linkers.
Caveat: Maximum conductivity values for Zr(dcphOH-NDI) and UU-100(Co) are read from plotted axes because exact source-data values were not supplied locally.
6 · Generality of the redox conductivity with other MOFs · Fig. 4 · Linked to 6 structured results
Zn(pyrazol-NDI) conducts primarily by redox hopping rather than band transport because the Zn nodes and NDI linkers are electronically localised and the linker geometry precludes direct pi-orbital overlap.
Caveat: Electronic structure is inferred from structural/electrochemical evidence rather than a direct electronic band measurement.
