Properties of Conducting 7,7,8,8-Tetracyano-p-quinodimethane Salts with 1,n-Bisalkane Dication Homologues

Article abstract of DOI:10.1021/j100326a057

1,n-Bis<1-(γ-picolinio)>alkane-(TCNQ)m salts are nonstoichiometric with m varying from 3.4 to 4.7 for n=2-7.The conductivity (compressed pellet, four-probe method, in the temperature range 230-310 K) varies with the alkyl chain length of the dications, the highest being 2 S cm^-1, for n=4 and m=4.6, with the lowest activation energy (0.033 eV).FT-IR and electronic absorption spectra are presented and discussed.On the basis of the results observed, a possible structure is proposed for these homologous salts.
