New π-conjugated system compounds were synthesized by pyromellitic diimide core coupled with side chain containing 1,2,4-triazole rings. The new compounds were characterized by some physical properties, FT-IR and 1H-NMR and the compounds showed a high melting point with some above 300 °C depending on high intramolecular attractive and the Vander Waals attraction between various substituent groups. The optical properties of the prepared compounds were investigated by UV–vis measurement and optical energy gap were estimated by about 2.85-4 e.v. Electro physical properties showed the compounds to behave as p-type semiconductor with acceptable mobility.
