Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
PXRD and FTIR support successful formation of analogous 2D M-HHTP MOF structures for Cu, Cu/Zn and Zn samples.
Caveat: Rietveld crystallite size and strain values were read from figure annotations rather than text tables.

In Cu/Zn-HHTP, Zn replaces Cu while preserving similar local Cu and Zn square-planar O coordination environments.
Caveat: Atomic ratio is reported approximately from EDX.
p003 · Results and Discussion · Table S1 and Figure S4 · Linked to 4 structured results
Replacing Cu with redox-inactive Zn suppresses THz photoconductivity by preventing electron trapping at metal bands and favouring strongly bound HHTP-localised excitons.
Caveat: Cu/Zn and Zn THz attenuation values are not tabulated numerically in the text; the extraction records the authors' qualitative comparison.
p005 · Results and Discussion · Figure 3 and Figure S11 · Linked to 3 structured results
High Cu-HHTP photoconductivity is attributed to mobile photoexcited holes transported through interlayer pi-pi interactions between HHTP ligands, while photoelectrons localise at Cu centres.
Caveat: DFT does not directly predict excited-state dynamics; the mechanism is inferred from combined OPTP, OTA, XTA and DFT evidence.
p005-p006 · Results and Discussion / Conclusion · Figure 5 · Linked to 4 structured results
Cu-HHTP reaches a reported photoconductivity of 65.5 S/m, the highest spectroscopic photoconductivity benchmark in the paper for catecholate-type porous MOFs.
Caveat: Photoconductivity is calculated from OPTP using the reported thin-film/sample-cell approximation and 3.5 um thickness.
p003-p004 · Results and Discussion · Table S3 · Linked to 3 structured results
THz-TDS temperature trends are interpreted as freeze-out of thermally activated free carriers and semiconductive ground-state behaviour in Cu-HHTP.
Caveat: The SI provides graphical THz-TDS curves without tabulated numeric values for absorption coefficient, refractive index or permittivity.
