Selected physicochemical properties of the thiophene imines with a free -NH2 group

This article presents selected physicochemical properties of the thiophene imines with a free -NH2 group. The study was focused on investigations of impact of substituent in imine bond structure on thermal, electrochemical and optical properties. The synthesized compounds tested as hole transporting materials in perovskite cells with the structure FTO/b-TiO2/m-TiO /perovskite /imine/Au. The advantageous effect of the presence of morpholine derivative and methylbenzene unit in imines on cells efficiency was found.
