Synthesis of Formula (3-4)
[0116]The compound C (1 g, 4.3 mmol), aniline (2 g, 21.5 mmol), 1-pyrenecarboxyaldehyde (0.991 g, 4.3 mmol), ammonium acetate (0.497 g, 6.45 mmol), 10 mL of toluene and 10 mL of acetic acid were heated for 4 hours. The reaction mixture was cooled to room temperature. The resulting solid was filtered and washed with ethanol and water to obtain the compound represented by the formula (3-4) (1.45 g, yield 65%). MS [M+H]+=519. 1H NMR (300 MHz, DMSO-d6): 7.28-7.32 (m, 5H), 7.68-7.73 (m, 6H), 7.88-7.82 (m, 6H), 8.04-8.18 (m, 5H)
synthesis example 3
Synthesis of Formula (3-10)
[0117]The compound C (1 g, 4.3 mmol), aniline (2 g, 21.5 mmol), terephthalaldehyde (0.289 g, 2.2 mmol), ammonium acetate (0.497 g, 6.45 mmol), 10 mL of toluene and 10 mL of acetic acid were heated for 4 hours. The reaction mixture was cooled to room temperature. The resulting solid was filtered and washed with ethanol and water to obtain the compound represented by the formula (3-10) (0.92 g, yield 60%). MS [M+H]+=711. 1H NMR (300 MHz, DMSO-d6): 7.0-7.08 (m, 4H), 7.28-7.32 (m, 7H), 7.4 (d, 2H), 7.5-7.53 (m, 4H), 7.68-7.73 (m, 2H), 7.88-7.82 (m, 4H), 8.08-8.12 (m, 2H)
synthesis example 4
Synthesis of Formula (4-1)
[0118]The compound C (2.32 g, 10 mmol), diaminomalenitrile (1.08 g, 10 mmol) and 10 mL of acetic acid were heated overnight. The reaction mixture was cooled to room temperature. The resulting solid was filtered and washed with ethanol and water to obtain the compound represented by the formula (4-1) (2.43 g, yield 80%). MS [M+H]+=306.
