EXAMPLE - 1,7-bisbromo-3,4,9,10-tetracarboxylic dianhydride (2.74 g) in butanol (200 ml) was sonicated for 10 minutes, 2-decyl-1-tetradecylamine (6.2 g) was added and the reaction mixture was heated at 80degreesC for 17 hours under nitrogen. Hydrochloric acid (20 ml) was added to the reaction mixture and stirred for 30 minutes. The reaction mixture was worked up to give diimide compound of formula (IIA) (4.9 g, 81%).
