Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
FTIR CO-band shifts support coordination of L to the PtNP surface and electronic withdrawal after Fe salt coordination in the PtNPs-FeL3 self-assembly.
Caveat: Assignment is spectroscopic and indirect; no single-crystal structure was reported.

The FeL3 coordination polymer directs organisation of ultra-small PtNPs into aligned lamellae with 3.2 nm line spacing; L-only PtNP controls aggregate without aligned lines.
Caveat: SI notes the hybrid system includes zones of NP lines distributed in larger areas where PtNPs are disorganised.

Spin crossover is retained in the PtNPs-FeL3 self-assembly but only partially, with 36% SCO from XAS and a 42% magnetic decrease.
Caveat: The SCO fraction estimate is stated to vary by about +/-10%; dry powder-state self-assembly loses SCO.
p004, journal p. 8183 · Magnetic and charge transport measurements · Fig. 4a · Linked to 2 structured results
Non-linear I-V behaviour in the PtNPs-FeL3 self-assembly at 300 K is presented as a Coulomb blockade signature.
Caveat: The SI shows I-V curves but no quantitative Coulomb blockade fitting parameters.
p005 · Supplementary information · Fig. S4 · Linked to 2 structured results
The current-temperature slope break in PtNPs-FeL3 devices is attributed to spin crossover, and the high-spin state is assigned as the more conducting state.
Caveat: Authors discuss possible transport-mechanism changes but consider them unlikely; device-to-device resistance varies due to non-homogeneous filling.
