Novel porphyrin‐grafted poly(phenylene vinylene) derivatives: Synthesis and photovoltaic properties

Feng, Jichang, Zhang, Qinghui, Li, Wang, Li, Yang, Yang, Mujie, Cao, Yong·2008·Journal of Applied Polymer Science

Abstract

A series of novel porphyrin‐grafted poly (phenylene vinylene) derivatives, Porp‐RO‐PPV, were synthesized by a simple two‐step method. These copolymers contain conjugated poly(phenylene vinylene) derivatives as polymer backbone and covalently linked porphyrin units as side chain, which were confirmed by FTIR and 1H NMR, and used for photovoltaic devices. The thermal, optical properties and sensitizing effect, and photovoltaic properties have been investigated. The emission spectra of Porp‐RO‐PPV copolymers revealed the existence of strong energy transfer from PPV backbone to porphyrin units. The energy conversion efficiency (ηe) of photovoltaic devices based on Porp‐RO‐PPV+PCBM reached 0.33% (78.2 mW/cm2, AM1.5) and porphyrin units in the copolymers showed good sensitizing effect at low concentration. © 2008 Wiley Periodicals, Inc.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Cao et al. synthesized several porphyrin-functionalized copolymers A1-A4 by two-step reactions, and the best PCE of 0.32% was obtained for the A1:PCBM combination.

    “Cao et al. synthesized several porphyrinfunctionalized copolymers 24 ( A1 -A4 ) by two-step reactions (Fig. 4), and the best PCE of 0.32% was obtained for the A1 :PCBM combination.”
  • Emission spectra indicated electron transfer from the PPV backbone to the porphyrin side-chain and then to PCBM.

    “Emission spectra indicated electron transfer from the PPV backbone to the porphyrin side-chain and then to PCBM.”
  • In the A1-A4 copolymers, PCE and Jsc decreased with an increase of porphyrin content.

    “However, the PCE and J sc decreased with an increase of porphyrin content in these copolymers.”

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.
