Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
White-light irradiation improves Schottky-device transport metrics, increasing SCLC conductivity and mobility while lowering series resistance and transit time for both compounds.
Caveat: Device data are from the reported thin-film Schottky geometry; raw I-V data are not supplied.

The article reports electrical/optoelectronic, magnetic, structural and computational data, but no porosity, thermoelectric or electrochemical performance measurements were found in the supplied main text or SI.
Caveat: Search is limited to assigned main and SI documents; no CIF/raw data files were fetched.

Changing the axial linker from 4,4'-BPY to PYZ switches the Cu(II) paddle-wheel assembly from a 1D polymer to a 0D tetranuclear complex.
Caveat: The paper attributes this primarily to linker N-N distance and steric effects; no alternative linker series beyond these two is tested.
1-2 · Abstract; Structural Analysis · Figures 2-3 · Linked to 4 structured results
Compound 1 is ferromagnetic at room temperature whereas compound 2 is antiferromagnetic at 300 K, consistent with different structure and charge-transfer behaviour.
Caveat: Mechanistic assignment relies partly on DFT and qualitative DOS/LDOS interpretation.
3 · Magnetic Properties · Figures 5-6; Table S4 · Linked to 6 structured results
Compound 1 is substantially more conductive than compound 2 in thin-film devices, with reported dc conductivity about 150 times higher.
Caveat: Conductivity is measured on spin-coated films; morphology/contact contributions are not deeply separated beyond impedance and Schottky analyses.
