Electron-phonon interactions of free charge-carriers in doped pi-conjugated polymers are conceptually described by 1-dimensional (1D) delocalization. Thereby, polaronic transitions fit the 1D-Froehlich model in quasi-confined chains. However, recent developments in conjugated polymers have diversified the backbones to become elaborate heterocylcic macromolecules. Their complexity makes it diffi...
The SCSC transformation of a 1D polymer [Cd(1,3-bdc)(4-spy)2]n produced a 2D polymer [Cd(1,3-bdc)(4-spy)(HT-ppcb)0.5]n through the [2+2] photodimerization reaction. Hydrothermal reactions of HT-ppcb with CdCl2, 1,3-H2bdc and H2O2 afforded another 2D polymer {[Cd(H2O)(1,3-bdc)(bpbpf)]·H2O}n in which HT-ppcb underwent in situ oxidation to form a unique furan-based ligand bpbpf.
An amphiphilic meta-ethynylpyridine polymer with chiral amide side chains was developed. The polymer was prepared by sequential Sonogashira reactions, and the product was soluble in polar and apolar solvents. The additive effects of metal salts on the polymer were examined in water and aqueous EtOH on the basis of UV-vis and CD spectra. The enhancement of the positive Cotton effect and hypochro...
The molecular packing in a polymer: fullerene bimolecular crystal is determined using X-ray diffraction (XRD), molecular mechanics (MM) and molecular dynamics (MD) simulations, 2D solid-state NMR spectroscopy, and IR absorption spectroscopy. The conformation of the electron-donating polymer is significantly disrupted by the incorporation of the electron-accepting fullerene molecules, which intr...
