New one- and two-dimensional p-conjugated materials containing a tetraoxa[8]circulene monomer are theoretically predicted on the basis of density functional theory techniques. These novel materials are predicted to demonstrate a promising hole/electron mobility properties which are typical for the ambipolar organic semiconductors. Furthermore, the growth of p-conjugation determines the strong visible light absorption of the studied systems in a great contrast to the initial lack of color of the tetraoxa[8]circulene compound. The synthesis of these new organic p-conjugated materials is an important task because of their potential practical applications in optoelectronic devices
