Abstract
Two series of new N-{4,6-bis[2-(het)arylvinyl]pyrimidin-2-yl}-substituted aromatic polycyclic imides were synthesized. The synthesized chromophores were characterized by UV and fluorescence spectroscopy, cyclic voltammetry, and quantum chemical density functional theory calculations. A change in the nature of aryl (hetaryl) moieties was found to cause changes in the optical properties of both solutions of these compounds and thin films prepared from these compounds. The replacement of the phthalimide moiety by the 1,8-naphthalimide one has led to a significant increase in the lowest unoccupied molecular orbital energy.
