Abstract In this study, two new thiophene based imine compounds (HA and HB) were obtained from the reaction of 2-amino-4-phenylthiophene-3-carbonitrile (1) or 2-amino-4-(naphthalen-2-yl)thiophene-3-carbonitrile (2) with 3-methoxy salicylaldehyde. Single crystals of compound HA were obtained by slow evaporation of a THF solution of the compound and its structure was determined by single crystal X-ray diffraction study. The structure of HA was solved in orthorhombic unit cell and P212121 space group with Rfinal value of 0.0505. The Hirshfeld surface analysis was used to evaluate the interaction sites within the structure of HA. The structure of compound HA is stabilized by CHimine····Nnitrile and CHthiophene····O) contacts. Electrochemical and photoluminescence properties of the compounds were investigated. Thermal properties of compounds HA and HB were investigated by TGA/DTA methods in the range of 20–900 °C. The electrochemical properties of the compounds were studied at different scan rates.
