An anisotropic, ordered layer structure was achieved using [P3HT20-Zn-PEO107] and carefully characterized by polarized optical microscopy (POM), AFM, polarized UV/Vis spectroscopy, and GI-SAXS/WAXS. The PEO-removed [P3HT20-Zn-PEO107] film was obtained after decomplexation with TEA-EDTA under mild conditions, and the selective removal of PEO domains was evidenced by UV/Vis and ATR-FTIR spectroscopy. Anisotropic photoconductivity of the magnetically aligned film was evaluated by flash-photolysis time-resolved microwave conductivity (FP-TRMC) measurements. The results indicated that the presence of insulating crystalline PEO segments diminished the photoconductivity along the P3HT backbone direction. ? 2020 Wiley-VCH GmbHAnisotropy; Crystallography; Fourier transform infrared spectroscopy; Magnetic fields; Nanocrystalline materials; Photoconductivity; Photolysis; Supramolecular chemistry; Tea; Ultraviolet visible spectroscopy; Zinc metallography; ATR FT-IR spectroscopies; Metallo-supramolecular; Oriented polymers; Polarized optical microscopy; Selective removal; Solvent evaporation; Time-resolved microwave conductivities; UV/ Vis spectroscopy; Polymer filmsjournal article10.1002/anie.202012284330519512-s2.0-85096633816
