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.
The authors explicitly caution that steady-state redox conductivity should not be calculated simply from transient-state Dapp because the measurements probe different regimes.
Caveat: This is an interpretive caveat from the authors, not a standalone measured value.
12007 · Transient-State vs Steady-State Redox Hopping · Figure 7 · Linked to 2 structured results
Maximum steady-state redox conductivity scales with linker percentage/hopping distance for NDI and PMDI redox pairs, so mixed-linker composition tunes conductivity in addition to applied potential.
Caveat: Several intermediate conductivity maxima are figure-axis estimates rather than tabulated values.
12007 · Tunable Steady-State Redox Conductivity in the Mixed-Linker Thin Film · Figure 7 · Linked to 4 structured results
The NDI/PMDI feeding ratio controls incorporated linker stoichiometry and the mixed-linker MOFs have statistically distributed linkers without homolinker domains detectable by the presented electrochemistry/composition evidence.
Caveat: No direct local-domain imaging or atomistic compositional map is reported; inference is from feeding-output correlation and redox-wave behaviour.
12001 · Results and Discussion · Figure S13 · Linked to 3 structured results
Transient apparent electron diffusion coefficient decreases when NDI sites are diluted from 100% to 20%, consistent with longer NDI-to-NDI hopping distances.
Caveat: Only 100% and 20% NDI Dapp values are explicitly reported in the main text.
12006 · Tunable Transient-State Dapp in the Mixed-Linker Thin Film · Figure 6 · Linked to 2 structured results
Pulsed spectrochronoamperometry identifies both thermoneutral homolinker hopping and thermodynamically driven heterolinker electron transfer from reduced PMDI states to NDI acceptors.
Caveat: Mechanistic assignment is spectroscopic and time-resolved but not supported here by independent microscopic mapping of charge locations.
