Procedure

A mixture of Intermediate D (1.00 g, 1.65 mmol), 6-bromo-2-hexyl-1H-benzo[de]isoquinoline-1,3(2H)-dione (720 mg, 2.0 mmol), potassium carbonate (276 mg, 2.0 mmol), CuI (382 mg, 2.0 mmol), and dimethylformamide (12 mL) was stirred under argon and heated at 160° C. for 3 days. After cooling, the reaction mixture was diluted with ethyl acetate (100 mL), washed with water (3×50 mL), dried over magnesium sulfate, and the solvent was removed under reduced pressure. The crude product was purified by column chromatography (silica gel, hexane/dichloromethane 1:1) and washing with ethanol to give 6-(4,7-bis(4-(N,N-diphenylamino)phenyl)-2H-benzo[d][1,2,3]triazol-2-yl)-2-hexyl-1H-benzo[de]isoquinoline-1,3(2H)-dione (Example 18), brown-violet crystals, 445 mg (30%). 1H NMR (400 MHz, CDCl3): δ 9.08 (dd, J=8.4 and 1.1 Hz, 1H, naphthalene), 8.74 (d, J=7.6 Hz, 1H, naphthalene), 7.69 (dd, J=7.3 and 1.1 Hz, 1H, naphthalene), 8.43 (d, J=8.1 Hz, 1H, naphthalene), 8.07 (d, J=8.8 Hz, 4H, p-phenylene), 7.85 (dd, J=8.4 and 7.3 Hz, 1H, naphthalene), 7.74 (s, 2H, benzotriazole), 7.28 (m, 8H, Ph), 7.21 (d, J=8.4 Hz, 4H, p-phenylene), 7.18 (m, 8H, Ph), 7.05 (tt, J=7.3 and 1.1 Hz, 4H, Ph). UV-vis spectrum (dichloromethane): λmax=381 nm. Fluorimetry (dichloromethane): λmax=481 nm.
