Embodiment 1
[0046] An organic electronic material based on phenanthrene and benzonitrile, the organic electronic material contains compound 2, and the synthetic route of compound 2 is as follows:
[0047]
[0048] The synthetic method of intermediate 2-1
[0049] In the flask, add o-bromoiodobenzene (52.2g, 184.5mmol), phenylacetylene (18.85g, 184.5mmol) and triethylamine (260mL), under nitrogen protection, add cuprous iodide (0.35g, 1.84mmol) and Triphenylphosphinepalladium chloride (0.5g, 0.7mmol), stirred at room temperature for 0.5h, then stopped the reaction, filtered, and concentrated to remove triethylamine to obtain 46.8g of yellow oily liquid, with a yield of 98%.
[0050] The synthetic method of intermediate 2-2
[0051] In the flask, add intermediate 2-1 (13.4g, 52.1mmol), p-chlorophenylboronic acid (8.5g, 54.4mmol) and potassium carbonate (14.4g, 104.2mmol), then add toluene (80mL), tetrahydrofuran (40mL) and deionized water (40mL), under the protection of nitrogen, add t...
Embodiment 2
[0063] An organic electronic material based on phenanthrene and benzonitrile, the organic electronic material contains compound 7, and the synthetic route of compound 7 is as follows:
[0064]
[0065] Synthesis of Intermediate 7-1
[0066] In the flask, under nitrogen protection, add intermediate 2-3 (5g, 12mmol), 3-cyano pinacol borate (4.1g, 17.9mmol), potassium carbonate (5.0g, 36mmol), 30mL toluene, 15 mL of ethanol, 15 mL of deionized water, dichloroditriphenylphosphine palladium (0.15 g), heated to reflux for 3 hours, cooled, separated, washed once with water, and concentrated to dryness. After separation by column chromatography, 3.5 g of white crystalline solid was obtained, with a yield of 74%.
[0067] 1 H NMR (400MHz, CDCl 3 ,δ):8.73-8.78(m,2H),7.63-7.74(m,2H),7.50-7.56(m,3H),7.46(s,1H),7.23-7.41(m,6H),7.07-7.11( m,2H).
[0068] Synthesis of compound 7
[0069] Under the protection of nitrogen, intermediate 7-1 (3g, 7.7mmol), 2,4-diphenyl-6-(3-phenylboroni...
Embodiment 3
[0072] An organic electronic material based on phenanthrene and benzonitrile, the organic electronic material contains compound 8, and the synthetic route of compound 8 is as follows:
[0073]
[0074] The synthesis method of compound 8 is the same as that of compound 2 in Example 1, except that 2,4-diphenyl-6-(3-phenylboronic acid pinacolate)-1,3,5-triazine is used instead of 2 ,4-Diphenyl-6-(4-phenylboronic acid pinacolate)
[0075] Except for -1,3,5-triazine, the yield was 68%.
[0076] 1 H NMR (400MHz, CDCl 3 ,δ):8.96-8.98(m,2H),8.88-8.91(d,1H),8.75-8.78(m,5H),8.11-8.14(m,1H),7.94-7.95(m,1H),7.75 -7.81(m,2H),7.55-7.65(m,10H),
[0077] 7.44-7.46(m,1H),7.21-7.35(m,7H).MS(ESI,m / z):[M+H] + :663.21.
