Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
CuHHTP-70 is less stable under X-ray exposure than CuHHTP-40, with Cu(I) becoming dominant after repeated XPS scans.
Caveat: This is an XPS beam exposure stability caveat and not necessarily a storage stability measurement.

Residual PMMA on transferred MOF films, especially CuHHTP-70, is proposed to passivate the surface, act as an electron trap, and hinder charge transport.
Caveat: Attribution is inferential from morphology, conductivity and literature on PMMA residues.

PMMA transfer does not compromise the crystalline Cu3(HHTP)2 phase, based on retained GIXRD MOF peaks.
Caveat: GIXRD also shows an amorphous polymer contribution from the support.

Using PAA/methanol instead of PMMA/chlorobenzene still gives a 40 C n-type and 70 C p-type trend, suggesting the carrier-type switch is not restricted to PMMA.
Caveat: PAA data are supporting-information comparative data; detailed methods and morphology are less extensive than for PMMA samples.

Drying/transferring electrodeposited Cu3(HHTP)2 films at the higher temperature switches the majority carrier type from n-type in CuHHTP-40 to p-type in CuHHTP-70.
Caveat: The films are polymer-supported after transfer, so residual polymer and adsorbed oxygen/water are part of the experimental context.
main p.1, article p.12404 · Abstract · Linked to 6 structured results
The authors attribute p-type conduction most likely to molecular oxygen/water adsorption acting as an electron acceptor and causing hole doping.
Caveat: The paper frames this as likely and notes further molecular dynamics and band-structure calculations are ongoing.
