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.
Cu3(HHTATP)2 composite electrodes outperform parent Cu3(HHTP)2 in three-electrode gravimetric capacitance at matched current density.
Caveat: Both are free-standing composite electrodes; pristine framework powder capacitance is not isolated.
29769 · Electrochemical Features · Figure S16; Table S3 · Linked to 2 structured results
Molecular-level pore tuning couples EDL and faradaic processes to deliver high aqueous supercapacitor capacitance.
Caveat: Dunn and Trasatti partitioning depend on model assumptions described in the SI.
29771 · Conclusions · Linked to 4 structured results
Pendant aromatic amines improve electrode wettability/hydrophilicity relative to Cu3(HHTP)2.
Caveat: Measured on composite electrodes, not bare single crystals/films.
29769 · Electrochemical Features · Figures 1c and S10 · Linked to 2 structured results
Modified electrode-electrolyte interactions from pendant amines lower interfacial charge-transfer resistance.
Caveat: Three-electrode EIS comparison is mainly qualitative in the extracted text; two-electrode Rct values are reported numerically.
29769 · Electrochemical Features · Figure S11 · Linked to 3 structured results
Pseudocapacitive response arises from amine/imine redox plus Cu+/Cu2+ redox processes.
Caveat: Amine/imine and Cu redox assignments rely on CV plus ex situ/held-potential XAS evidence.
