ELECTRICAL CONDUCTIVITY IN TCNQ SALTS OF BIS(4-DIMETHYLAMINOPHENYLIMINO) SULFUR AND ITS STRUCTURAL ANALOGUES.

Article abstract of DOI:10.1080/00268948208071021

Four compounds, N,N,N prime ,N prime -tetramethyl-p-phenylene diamine, N,N,N prime ,N prime -tetramethyl-benzidine, 4,4 prime -bis(dimethylamino)azobenzene and bis(4-dimethylaminophenylimino)sulfur (BAPIS) were examined electrochemically and spectroscopically. Each was shown to be a fairly good donor forming in its first oxidation state a radical-cation. The latter two materials surprisingly exhibited only single one-electron oxidations. Conformational flexibility about the -NSN- unit was studied by NMR spectroscopy and ab initio molecular orbital theory. The experimental DELTA G* for a cis-trans to trans-cis interconversion in BAPIS was found to be 11. 9 kcal/mole. The four donors all form 1:1 adducts with TCNQ. The compaction resistances of the complexes have been measured as a function of temperature. Of the four, (BAPIS)(TCNQ) appears to be a one-dimensional material. The other three complexes behave as typical mixed stack organic semiconductors.
