Reaction Steps

3,7-Bis-(4-bromo-phenyl)-1H,5H-pyrrolo[2,3-f]indole-2,6-dione (1.500 g, 3.023 mmol) (1.3) is dissolved into anhydrous dimethylformamide (60 cm3) and then potassium carbonate (4.178 g, 30.23 mmol) and 7-bromomethyl-pentadecane (2.308 g, 7.558 mmol) are added. The resulting mixture is heated to 90° C. for 21 hours before been cooling down, poured into methanol (400 cm3), filtered and washed with water (200 cm3) to recover the pure product (1.525 g, Yield: 53%). NMR (1H, 300 MHz, CDCl3): δ 7.61 (d, J=8.7 Hz, 4H), 7.57 (d, J=8.6 Hz, 4H), 6.29 (s, 2H), 3.50 (d, J=7.3 Hz, 4H), 1.76 (m, 2H), 1.28 (m, 48H), 0.86 (t, J=7.1 Hz, 12H)
