Abstract

A series of small organic molecules were synthesized by exploiting the bay and imide positions of the perylene nucleus. The synthesized compounds 1–11 were characterized by spectroscopic and elemental analyses. These molecules show yellowish color in solution and are highly soluble in dichloromethane. Compound 7 shows a bandgap of 1.7 eV and a Stokes shift of 27. From these results, we infer that this compound can serve as structural template in the design of organic electronics. Moreover, compound 7 shows higher Td (370°C) and Tg (132°C) values, which reflect its high thermal stability.
