Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Weakly agglomerated flake-like particles with very small length-to-width aspect ratios below 1 are best for MOF supercapacitors.
Caveat: The conclusion is based on Cu3(HHTP)2 samples and two electrolyte systems; broader MOF generalisation requires future work.
p007 / journal p9216 · Conclusions · Linked to 3 structured results
BET surface area does not necessarily predict electrolyte-ion-accessible surface area or capacitance for these Cu3(HHTP)2 samples.
Caveat: The explanation invokes possible residual solvent or impurities blocking B-CuHHTP pores during N2 sorption.

DMF-modulated B-CuHHTP likely has increased layer stacking shift and near-eclipsed stacking compared with A- and C-CuHHTP.
Caveat: The authors call for future work to examine the impact of modulator identity on layered-MOF structures.
p003 / journal p9212 · Results & discussion · Fig. 2; SI Fig. S4 · Linked to 2 structured results
With EMIM-BF4 ionic liquid, A-CuHHTP strongly outperforms B- and C-CuHHTP because EMIM+ and BF4- penetration into rod-like/agglomerated pore networks is impeded.
Caveat: Authors note that future adsorption studies are needed to confirm ion uptake within the porous materials.

Weakly agglomerated flake-like A-CuHHTP gives better rate capability in organic electrolyte because many short pores improve ion accessibility.
Caveat: A- and B-CuHHTP have similar capacitance at low current density in organic electrolyte, so the key advantage is rate capability at shorter charging times.
p005-p006 / journal p9214-p9215 · Results & discussion · Fig. 4 · Linked to 4 structured results
Changing the modulator in the Cu3(HHTP)2 synthesis is an effective way to regulate particle morphology and agglomeration.
Caveat: Authors state that examining and rationalising formation mechanisms is beyond the scope of the work.
