Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The conductive 2D MOF@Pc/DNH hydrogel enables high TENG, supercapacitor and sensing performance for a self-powered underwater sensing microsystem.
Caveat: Application metrics are device-level and depend on composite geometry and system design, not solely intrinsic MOF conductivity.

The authors argue the materials have less adverse environmental impact because CMC/PVA are eco-friendly/biodegradable and prior work indicates low toxicity of cobalt-MOF and CoPc.
Caveat: Environmental safety is argued from literature and matrix composition; no new cytotoxicity or degradation data are reported in this paper.
9 · Results and Discussion
2D MOF@Pc enhances compactness of the polymer hydrogel network, reducing average pore size and improving anti-swelling behaviour via physical interactions and exposed Co coordination with the polymer matrix.
Caveat: Anti-swelling/depth-response claims are mainly application demonstrations; pore-size data are SEM-derived hydrogel morphology.

Pc is successfully incorporated into/decorates 2D MOF@Pc and coordinates to Co through N-Co interactions.
Caveat: Exact crystallographic structure and formula are not reported; assignment is based on spectroscopy, diffraction shifts and modelling.

Decorating 2D MOF with Pc increases the conductivity of the corresponding DNH hydrogel from 50 to 78 S m-1, a 56% increase over pristine 2D MOF/DNH.
Caveat: Conductivity is reported for hydrogel composites, so it reflects both nanofiller electronic changes and composite/matrix connectivity.
2,5 · Results and Discussion · Figure 2i · Linked to 3 structured results
Pc incorporation enhances electron transport in 2D MOF@Pc by N pz-Co dxy / d-pi hybridisation, elevating the Co dxy orbital energy level and expanding electron delocalisation.
Caveat: Mechanism combines DFT models and spectroscopy; direct transport measurement is on hydrogel composites rather than isolated MOF pellets.
