Sumanene (C۲۱H۱۲) is the smallest bowl-shaped molecule containing a central benzene ring, which is alternately surrounded by another ۳ benzene rings and cyclopentadiene rings. In this study, the effect of various electron donor and receptor substitutions on its structure, electrical and optical properties were investigated. The results showed that the electron-bonding and electron-donor-acceptor groups to sumanene greatly affected the electrical properties. In contrast, the most significant effect occurred when NO and CH۲Li substitutions were at the two positions simultaneously. These substitutions also greatly influenced optical properties and significantly increased its polarization and polarization values. The most significant effect occurred when BH۲ and NCH۳Li were replaced in position ۱. Finally, the absorption spectrum of the substituted molecules was examined when the BH۲-NCH۳Li groups were in position ۱.
