Four main chain polymeric metal complexes (P1–P4) based on 1,10‐phenanthroline metal complexes via the Heck coupling have been synthesized and characterized by Fourier transform infrared spectroscopy, 1H NMR, UV–Vis absorption, photoluminescence spectroscopy, gel permeation chromatography, thermogravimetric analysis, differential scanning calorimetry, elemental analysis, and cyclic voltammetry. To investigate their photovoltaic properties, the dye‐sensitized solar cells based on these polymers dyes are studied, under the illumination of AM 1.5G, 100 mW/cm2. The study results show the four polymers exhibit good thermally stable and the solar cells based on them have good device performance, and the maximum power conversion efficiency is up to 0.735% for the solar cells based on P3 with a short‐circuit current (Jsc) of 1.68 mA/cm2 and an open‐circuit voltage (Voc) of 0.62 V.

Four main chain polymeric metal complexes (P1-P4) based on 8-hydroxyquinoline metal complexes have been synthesized by the Heck coupling and characterized by gel-permeation chromatography, Fourier transform infrared spectroscopy, proton-nuclear magnetic resonance, thermogravimetric analysis, ultraviolet-visible absorption, photoluminescence spectroscopy, elemental analysis, and cyclic voltammetry. The applications of these polymers as dye sensitizers in dyesensitized solar cells (DSSCs) are also studied. The study results show that the solar cells have good device performance with power conversion efficiency of P1-P4 up to 2.17, 2.04, 2.45, and 2.18%, respectively. The highest power conversion efficiency of DSSCs is up to 2.45%, for P3 consisting of alkoxy benzene unit and Cd-metal complex under the illumination of air mass 1.5 G, 100 mW cm 22 . POLYM.

Four novel donor À p-bridge À acceptor (D À p À A) polymeric metal complexes (P1-P4) based on 8-hydroxyquinoline metal complexes were synthesized and tested for their performance in dye-sensitized solar cells (DSSCs). The polymeric metal complexes dyes use alkoxy benzene or alkyl fluorene as the electron donor and C¼C as p linker; the 8-hydroxyquinoline derivative complex part was used as the electron acceptor and diaminomaleonitrile was used as ancillary ligand. The two strongly electron-withdrawing cyano groups in the polymer structure can provide an efficient charge transport in the intramolecular between donor and acceptor parts. The thermal, photophysical, electrochemical and photovoltaic properties of these copolymers were investigated by TGA, differential scanning calorimetry, cyclic voltammetry and cureent density-voltage curves, and the results showed that dye containing complex Zn(II) and alkoxy benzene unit benefited the generation of photocurrent and open-circuit voltages, and a maximum power conversion efficiency of 1.91% (P2) was obtained, with an open-circuit voltage of 0.71 V, a short-circuit current density of 4.23 mA cm À2 , and a fill factor of 38.6% under AM1.5G irradiation. The study results also show that the four polymers exhibit good thermal stability, indicating that these polymeric metal complexes are suitable for the fabrication processes of optoelectronic devices.
