Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Cu3(HHTT)2 films can be prepared on PI substrates as flexible photodetectors with strong mechanical stability under repeated bending.
Caveat: Photocurrent retention is described qualitatively in text, although Figure 4c plots the data with four-device error bars.

Pristine Cu3(HHTT)2 thin-film photodetectors show broadband response from UV to MIR (370-3400 nm), broader than comparison solution-processed photodetectors listed in the SI.
Caveat: Responsivity at the long-wavelength end is substantially lower and was visually estimated from a figure for this extraction.

The Cu3(HHTT)2 optical synapse exhibits STP/PPF/LTP-LTD behaviour and supports high simulated ANN recognition accuracy.
Caveat: Recognition accuracy is simulation based, using measured device LTP/LTD characteristics rather than a physical neural-network array.
p007-p008 · Results and Discussion · Figure 5 · Linked to 4 structured results
Layer-by-layer growth on OH-functionalised substrates yields highly oriented wafer-scale Cu3(HHTT)2 films under optimised ethanolic conditions.
Caveat: High-concentration films show random orientation; solvent and concentration control film quality strongly.
p003 · Results and Discussion · Figure 1; Figure S6 · Linked to 4 structured results
Cu3(HHTT)2 thin films are semiconducting and their carrier transport is dominated by phonon-assisted hopping through localised states, with different regimes across temperature.
Caveat: Authors note the AC-conductivity empirical fitting cannot be perfect for complicated hopping systems.
