7‐regioisomers of dinitro‐substituted perylene bisimides (1a—1b and 2a—2b) were synthesized under mild condition in high yields. The 1,6‐ and 1,7‐regioisomers were successfully isolated from the regioisomeric mixture using conventional methods of separation and subsequently characterized by 500 MHz 1H NMR spectroscopy. This is the first time when 1,6‐dinitroperylene bisimides (1a—1b) are obtained in pure form.

1,7-Dinitroperylene bisimides (1a-1b) and 1-nitroperylene bisimides (2a-2b) were synthesized under mild condition in high yields, and were characterized by FT-IR, H-1 NMR, UV-vis, HRMS spectra, cyclic voltammetry, and thermogravimetric analyses. These compounds are stable up to 260 degrees C according to thermogravimetric analyses. They undergo two quasi-reversible one-electron reductions in THF at modest potentials. The nitro functionalities provide stability of n-type charge carriers by lowering the LUMO to resist ambient oxidation. (C) 2010 Elsevier Ltd. All rights reserved.
