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.
PXRD patterns indicate parent and imidazole-loaded MOFs retain crystallinity after water exposure and EIS testing under reported conditions.
Caveat: Stability claim is based on PXRD pattern consistency; no long-term chemical-leaching data were reported in the extracted text.

Increasing imidazole loading drives MIL-88B from small-breathing to large-breathing states, expanding the unit cell and producing denser imidazole-mediated hydrogen-bonding networks.
Caveat: Cell parameters are from Le Bail refinement; hydrogen-bonding details are supported partly by simulations.

Functional groups can improve water-mediated conduction, but in imidazole-loaded MIL-88B the acid/base groups can hinder carrier mobility; pristine Im@MIL-88B-LB outperforms NH2 and SO3H analogues.
Caveat: Mechanistic interpretation about restricted imidazolium motion is inferred from conductivity and simulations rather than directly imaged dynamics.

A rigid larger-pore MIL-101 analogue loaded with imidazole conducts less well than Im@MIL-88B-LB, supporting the paper's claim that flexible breathing and self-adapted pore size matter, not simply larger pore volume.
Caveat: MIL-101 was used as a first-hand rigid larger-pore comparison, but detailed MIL-101 porosity values were not tabulated in the extracted SI.

Im@MIL-88B-LB gives the highest reported first-hand conductivity in this paper, 8.93 x 10^-2 S cm^-1 at 60 deg C and 95% RH, despite lacking added functional groups.
Caveat: The broader 'highest among imidazole-loaded proton conductors' comparison relies on literature table values not extracted as first-hand evidence.
p007 · Conclusion · Linked to 1 structured result
Imidazole loading lowers the activation energy from 0.41 eV in MIL-88B to 0.17 eV in Im@MIL-88B-LB, consistent with a Grotthuss-like proton hopping pathway in a continuous hydrogen-bond network.
Caveat: Grotthuss assignment is mechanistic interpretation from low activation energy and network formation.
