Abstract

Oligomers of the electroactive polymer poly(p-phenylene vinylene (PPV) were oxidatively doped in dilute CH₂Cl₂ solution with SbCl₅. In the dimer and trimer cases, stable charged species are formed which have characteristics similar to bipolarons formed during the oxidative doping of PPV, with ω_o/Δ splittings deep in the gap very similar to those found in PPV. Similar splittings are found in the tetramer, but the lack of oligomer solubility hindered detailed measurements. The bipolaron-like intermediates formed by chemical oxidation exhibit weak confinement qualitatively similar to the PPV bipolarons formed electrochemically or by photoinduced absorptions.

Synthesis of electrically conducting copolymers with short alternating conjugated and non-conjugated blocks
1994, Polymer
Six copolymers with short alternating conjugated and non-conjugated blocks were synthesized using the Wittig reaction. The conjugated block consists of two and one-half units of p-phenylene vinylene with methoxy groups substituted at the 3 and 5 positions of the flanking phenyl rings. These rigid blocks are linked to flexible linear alkyl chain spacers by ester groups. The polymers, characterized by ¹³C n.m.r., FTi.r., elemental analysis, g.p.c. and d.s.c. are soluble and fusible. Free-standing films were cast from chloroform solutions and showed electrical conductivities ranging from 10⁻³ to 10⁻² S cm⁻¹ upon doping by iodine vapour at room temperature.
Experimental and theoretical studies of the electronic structure of Na-doped poly (para-phenylenevinylene)
1993, Chemical Physics Letters
The electronic structure of sodium-doped poly (p-phenylenevinylene), or PPV, has been studied using photoelectron spectroscopy, UPS and XPS. Upon doping, two new states are created in the previously forbidden electronic bandgap. No finite density- of-states is observed at the Fermi energy. The UPS spectra are analysed with the help of VEH-level quantum chemical calculations. It is determined that the Na-doping of PPV results in the formation of bipolaron bands in the otherwise forbidden energy gap at saturation doping. These results are in contrast with the case of poly-hexyl-thiophene doped from NOPF₆, where the existence of a finite density-of-states at E_F and a stable polaron lattice was observed at saturation doping at room temperature. This work represents the first direct measure of multiple, resolved gap states in a doped conjugated polymer.
Anion and cation absorption spectra of conjugated oligomers and polymer
1993, Synthetic Metals
The absorption spectra of chemically oxidized and reduced phenylenevinylene oligomers and the phenyl-substituted polymer are reported. Based upon the variation of transition energy with chain length at constant spectral shape and the agreement between photoinduced and chemically induced absorption, it is proposed that at moderate doping levels the absorption is due to a Franck-Condon allowed transition of radical anions and cations not reflecting polaron binding energies.
Anion and cation absorption spectra of conjugated oligomers and polymers
1992, Chemical Physics
The absorption spectra of chemically oxidized and reduced oligo(phenylenevinylene)s, 2,5-distyryl-thiophene, and poly(phenylphenylenevinylene) are reported. The essential conclusions are: (i) In all cases it is the radical ion that is the energetically favored species. (ii) OPV forms divalent anions in the course of a second reduction step while PPPV forms divalent anions and cations in the presence of an excess of reductant or oxidant. (iii) Oxidation/reduction of the polymer is a consecutive process starting with those chain segments having the longest effective conjugation lengths. (iv) The polaron concept is found inappropriate for spectral analysis. Instead, it is proposed that the spectra have to be assigned to transitions among molecular orbitals of the oligomers and polymer chain segments, respectively.
Oxidative doping studies of PTV oligomers
1991, Synthetic Metals
Oligomers of the electroactive polymer poly(2,5-thienylene vinylene) (PTV) were oxidatively doped with dilute CH₂Cl₂ solution with SbCl₅. In all cases (dimer, trimer, tetramer and pentamer) stable bipolaron-like charged species are formed with ω_o/Δ splittings deep in the gap (ω₀/Δ = 0.36 for PTV dimer) and similar to those found in PTV itself (ω₀/Δ = 0.31). In contrast to PPV oligomers, polaronic-like charge states can also be formed by careful control of oligomer-oxidant ratio.
