Recently, there has been a significant interest in donor-acceptor systems for organic electronic applications. Researchers are actively working to enhance the properties of molecules by modifying individual components. 2,1,3-Benzothiadiazole (BTD) is commonly utilized as an acceptor unit owing to its impressive optoelectronic characteristics and its ability to form efficient luminophores when paired with donor units. In this study, a synthesis method was developed to create symmetrical luminescent molecules comprised of a BTD core as the electron-withdrawing component and thiophene and benzene moieties. This synthesis was accomplished through the direct arylation reaction. Additionally, molecules with various terminal substitutions, such as trimethylsilyl derivatives, as well as derivatives with hexyl, octyl, 2-ethylhexyl and decyl chains, were synthesized to examine their crystal packing behavior. The emission-luminescent properties of these derivatives in diluted solutions within tetrahydrofuran, as well as their thermal characteristics through differential scanning calorimetry and thermogravimetric analysis, were studied to assess the impact of the terminal groups.
