New conjugated polymer nanoparticles with high photoluminescence quantum yields for far-red and near infrared fluorescence bioimaging
Open accessAbstract
The development of new aqueous conjugated polymer nanoparticles with high photoluminescence quantum yields (PLQYs) at the far red and near infrared (NIR) spectral regions (>650 nm) as alternative polymer probes for fluorescence imaging is reported.

The extent of inter- and intrachain interactions in Pdots can partially be controlled through the type of copolymer used and the condition on nanoparticle preparation.
“Furthermore, the extent of inter- and intrachain interactions in Pdots can partially be controlled through the type of copolymer used and the condition on nanoparticle preparation.169”

In contrast to previous studies, the observed enhancement in brightness of Pdots upon fluorination was assigned to the presence of unfused and less-rigid polycyclic monomer building blocks, which reduced the planarity of the conjugated polymer chains in the Pdots through the anchoring of fluorine atoms.
“However, in contrast to previous studies, the observed enhancement in brightness of Pdots upon fluorination was assigned to the presence of unfused and less-rigid polycyclic monomer building blocks, which reduced the planarity of the CP chains in the Pdots through the anchoring of fluorine atoms.”

A favorable effect of acceptor fluorination was observed in a series of far-red/NIR emissive D-A conjugated polymers composed of thiophene donor and quinoxaline acceptor units.
“Similarly, a favorable effect of acceptor fluorination was observed in a series of far-red/NIR emissive D-A CPs that compromise of thiophene donor (T) and quinoxaline (Q) acceptor units.169”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
