PHOSPHORUS SULFUR AND SILICON AND THE RELATED ELEMENTS
Relation of the electrical conductivity as a function of temperature and th
e molecular structure data including infrared and ultraviolet spectra of p-
methoxybenzylidene-2-amino-3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophene and
p-methoxybenzylidene-diphenylphosphine-2-amino-3-cyano- 4,5,6,7-tetrahydrob
enzo[b]thiophene compounds has been investigated. The results of the electr
ical conductivity, thermal activation energies obtained from electrical con
ductivity measurements as well as the energy gaps calculated from ultraviol
et (UV) spectra in the solid state are consistent with those of semiconduct
or materials. The delocalized-pi-electrons in addition to the lone pairs of
electrons on nitrogen atoms of azomethine groups of the two compounds were
considered the main sources participating in the conduction processes.
