摘要: Abstract Charge transport through polymer films containing the tetracyanoquinodimethane (tcnq) structure in chain and swollen with acetonitrile solvent has been studied as a function of film composition. Variation composition was achieved by synthesis tcnq terpolymer casting blended polyester an isomorphic benzene ring place structure. Formation uniform blends at room temperature below indicated for neutral polymers, but phase separation takes on repeated cycling between 0 −1 oxidation states. Redox center site-site interactions were probed following dimer formation tcnq.− radical anion charge process measured chronocoulometric Cottrell slopes. ESR cyclic voltammetric data indicate that interchain, not occur reduced films.
