Sumanene (C21H12) is the smallest bowl-shaped molecule containing a central benzene ring, alternately surrounded by another 3 benzene rings and cyclopentadiene rings. This study investigated the effect of various electron donor and receptor substitutions on its structure, electrical and optical properties. 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 CH2Li substitutions were at the two positions simultaneously. These substitutions also greatly influenced optical properties and significantly increased polarization and polarization values. The most significant effect occurred when BH2 and NCH3Li were replaced in position 1. Finally, the absorption spectrum of the substituted molecules was examined when the BH2-NCH3Li groups were in position 1.
