Conjugated Polymer–Porphyrin Complexes for Organic Electronics
Abstract
We present the synthesis of novel conjugated polymer-porphyrin complexes for use in organic electronics. Linear and star-shaped platinated porphyrins were attached to regioregular poly(3-hexylthiophene-2,5-diyl) (P3HT) arms to investigate whether porphyrin stacking and increased dimensionality can be used to control polymer morphology. The novel materials display similar optical properties to P3HT, but give higher mobilities when used in organic field-effect transistors. Atomic force microscopy measurements show that incorporation of only a small amount of porphyrin into the conjugated polymer backbone leads to increased aggregation. These materials demonstrate that polymer morphology and performance can be tuned and enhanced effectively through the use of conjugatively linked porphyrins.

This can be explained on the basis of inefficient energy transfer from the polymer backbone to the porphyrin core because of the poor spectral overlap of the two species.

Platinum in porphyrin could enhance the direct intersystem crossing rate of P3HT singlet excitons that is responsible for photocurrent loss by triplet formations, a common loss pathway in OSCs.
“Moreover, platinum in porphyrin could enhance the direct intersystem crossing (ISC) rate of the P3HT singlet excitons that is responsible for photocurrent loss by triplet formations, a common loss pathway in OSCs.”

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.
