Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ni-Nd PMOFs show broad substrate scope for substituted benzyl alcohols and benzylamines under 12 W white light in air, with alcohol conversions 70-93% and benzylamine conversions 70-89%.
Caveat: Substrate-scope values are read from rendered SI page images because the SI text layer omits the table body.
5-6 · Table S2-S3 · Table S2; Table S3 · Linked to 4 structured results
The paper reports photoelectrochemical photocurrent/EIS and band-alignment data, but no direct dark electrical conductivity, mobility, thermoelectric, Seebeck, Hall, or four-probe transport measurement.
2 · Characterization procedures · Linked to 2 structured results
Ni-Nd PMOFs form a 3D porous framework with monoclinic C2/c crystallography and structure-derived pore dimensions of 21.514 A by 26.536 A.
Caveat: Main text says 'trigonal' but SI Table S1 reports monoclinic C2/c; the extraction follows Table S1.
6 · 3.1 Material characterization · Fig. 3; Table S1 · Linked to 4 structured results
Embedding Ni or Co in the porphyrin unit with Nd nodes improves photogenerated electron transfer relative to monometallic Nd PMOFs, with Ni-Nd PMOFs showing the strongest photocatalytic performance.
Caveat: Photocurrent and EIS numeric values are visual estimates; photocatalysis performance values are exact table values.
7 · 3.1 Material characterization · Fig. 6 · Linked to 4 structured results
Ni incorporation lowers PL intensity, increases transient photocurrent, and decreases the EIS semicircle, indicating more efficient charge separation and electron transport.
Caveat: The paper does not report fitted transport parameters or electronic conductivity; this is a photoelectrochemical interpretation.
6-7 · 3.1 Material characterization · Fig. 6 · Linked to 3 structured results
Photogenerated electrons reduce O2 to superoxide, and superoxide is proposed as the main reactive radical in benzyl alcohol oxidation and benzylamine coupling.
Caveat: Mechanistic claim is based on scavenger and EPR evidence, not direct quantification of all intermediates.
