Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Cu-THQ-BPY exhibits higher gravimetric capacitance and Cdl than Cu-THQ, consistent with improved ion accessibility to interior pores.
Caveat: Capacitance of pristine Cu-THQ at 10 mV s-1 is read from the plot, while Cu-THQ-BPY and Cdl values are text-reported.

A physical Cu-THQ/BPY mixture does not reproduce the structural or transport signature of coordinated BPY insertion.
Caveat: The physical-mixture XRD result is qualitative; exact diffraction intensities are not tabulated.

Postsynthetic BPY insertion transforms layered 2D Cu-THQ into a 3D Cu-THQ-BPY framework.
Caveat: No CIF file was supplied; assignment rests on PXRD/simulation/Pawley and spectroscopic evidence available in the paper/SI.
main p.3 · Results and Discussion · Figure 1 · Linked to 6 structured results
BPY insertion increases measured surface area and accessible pore metrics relative to pristine Cu-THQ.
Caveat: The paper notes BET surface area can be influenced by crystallinity and interparticle aggregation, so ECSA is used as a complementary accessibility metric.
main p.4 · Results and Discussion · Figure S9; Table S3 · Linked to 7 structured results
Strong d-pi conjugation and similar band alignment are retained after BPY insertion, despite reduced bulk conductivity.
Caveat: Bandgap and frontier-orbital values are mainly graphical; no exact table values were reported.
main p.4 · Results and Discussion · Figures S10-S13 · Linked to 2 structured results
Pyrazine does not insert into Cu-THQ under the same optimised conditions used for BPY insertion.
Caveat: Conclusion is restricted to the reported PYZ conditions; alternate PYZ insertion conditions were not demonstrated.
main p.4 · Results and Discussion · Figure S14 · Linked to 1 structured result
BPY pillaring decreases bulk electrical conductivity, attributed to enlarged interlayer distance reducing out-of-plane pi-pi orbital overlap.
Caveat: Most ratio-specific conductivity values are graphical estimates from Figure 4a rather than printed values.
