A Very Low Band Gap Diketopyrrolopyrrole–Porphyrin Conjugated Polymer
Abstract
A porphyrin-diketopyrrolopyrrole-containing polymer (poly(porphyrin-diketopyrrolopyrrole) (PPDPP)) shows impressive molar absorption coefficients from λ=300 to 1000 nm. The photophysical and structural properties of PPDPP have been studied. With PPDPP as the electron donor and [6,6]-phenyl C 71 butyric acid methyl ester (PC 71 BM) as the electron acceptor, the bulk heterojunction polymer solar cell showed overall power conversion efficiencies of 4.18 and 6.44 % for as-cast and two-step annealing processed PPDPP:PC 71 BM (1:2) active layers, respectively. These results are quite impressive for porphyrin-containing polymers, especially when directly included in the π-conjugated backbone, and offer interesting perspectives for the design of new materials based on this chromophore.

Combining porphyrin and DPP units to construct a donor polymer is a promising idea, and it has been successfully used to construct efficient donor small molecule materials.
“Thus, it is a promising idea to combine these units to construct the donor polymer, and it has been successfully used to construct e ffi cient donor small molecule (SM) materials. 49”

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.
