✦ Synopsis
Abstract
Thermally stable and semiconducting poly‐Schiff bases are synthesized by condensing 4,4′‐diacetyl diphenyl ether with o‐, m‐, and p‐phenylene diamines, benzidine, and ethylene diamine under different experimental conditions. These bases are insoluble in common organic solvents. They are characterized by infrared (IR) and viscosity measurements, thermal analysis, and the study of electricel properties at various temperatures. Variation of electrical conductivity σ with temperature followed the empirical relation σ = σ~0~e^−E*/kT^.
