Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Because Cu3BTC2 films can be grown on many substrates, their conversion offers a route to conductive Cu(TCNQ) on nonplanar or device substrates.
Caveat: Actual devices beyond simple Au-pad I-V structures were not demonstrated in this paper.
p009 / 39408 · Conclusions · Linked to 3 structured results
The TCNQ/MeOH conversion is not limited to Cu3BTC2; a PCN-14 film also shows Cu(TCNQ) phase I signatures after infiltration.
Caveat: Only SI GIXRD evidence is supplied; detailed PCN-14 synthesis and quantitative conversion are not reported.
p007 / 39406 · Chemical Processes · Figure S4 · Linked to 1 structured result
Cu3BTC2 thin films react with methanolic TCNQ to form dense conductive Cu(TCNQ) films rather than merely guest-loaded TCNQ@Cu3BTC2.
Caveat: For thinner films, AES still shows small oxygen contributions; complete phase assignment is strongest for 20- and 50-cycle films.
p001 / 39400 · Abstract · Linked to 3 structured results
Amorphous SiO2/Si(001) gives a narrower Cu3BTC2 crystallite-size distribution than polycrystalline ITO.
Caveat: Comparison is for 4-cycle films and based on AFM histogram analysis.
p008 / 39407 · Enhanced Growth · Figure 10 · Linked to 2 structured results
Bimodal Cu3BTC2 growth on polycrystalline ITO is attributed to compound crystals where merged crystallites enable accelerated layer growth.
Caveat: Growth model is a proposed mechanism based on AFM morphology and histogram analysis.
p008 / 39407 · Conclusions · Linked to 3 structured results
The conversion involves mass transport through solution and is not controlled by the initial Cu3BTC2 crystallite morphology.
Caveat: Mechanistic inference from morphology changes; no direct in situ transport measurement is reported.
p008 / 39407 · Conclusions · Linked to 3 structured results
Methanol is identified as the initiator/electron source for the TCNQ-induced conversion, with water or trace moisture also likely involved.
Caveat: The role of water is inferred by comparison with prior anhydrous/aprotic solvent reports, not isolated experimentally here.
p009 / 39408 · Conclusions · Linked to 3 structured results
Cu3BTC2 powder converts only partially because large grains develop a nonporous Cu(TCNQ) shell that slows diffusion to the core.
Caveat: Shell/front mechanism is inferred from incomplete PXRD conversion and particle-size comparison.
p006 / 39405 · Partial Conversion · Linked to 2 structured results
Chemical conversion from insulating Cu3BTC2 to Cu(TCNQ) increases conductivity by about ten orders of magnitude.
Caveat: Conductivity uses assumed 100 nm thickness; parent value is reported as an upper bound.
