Preparation of elastomeric ionene polymers containing 4,4′-bipyridinium or 1,2-bis(4-pyridinium)ethylene ring and the conductivity of their tcnq salts

ABSTRACT Elastomeric ionene polymers containing 4,4′-bipyridinium (BP) or 1,2-bis(4-pyridinium)ethylene (BPE) ring were prepared by the Menschutkin reaction of 4,4′-bipyridine or

1,2-bis(4-pyridyl)ethylene with an alkyliodide-terminated prepolymer derived from poly(propylene glycol) (PPG). Resistivity (ρ) and activation energy for conduction (_E_a) were measured for

the 7,7,8,8-tetracyanoquinodimethane (TCNQ) salts of these elastomeric ionenes. The values of ρ were 26.7 Ωcm and 24.8 Ωcm, and the values of _E_a were 0.077 eV and 0.079 eV for

(BP-PPG)–TCNQ complex salt and (BPE-PPG)–TCNQ complex salt, respectively. The complex salts were processible from solutions in the form of flexible films. A microheterogeneous structure of

continuous conduction columns composed of TCNQ˙̅ and TCNQ° and the poly(oxypropylene) chain brought about a high conductivity and favourable mechanical properties. These TCNQ salts were

stable in an ambient condition, and the values of ρ at the storage time of about 300 days were nearly twice as large as the initial values. SIMILAR CONTENT BEING VIEWED BY OTHERS EFFECT OF
