[0049]
[0050] Organic electroluminescent chromophore 1
[0051] The synthetic route is as follows:
[0052]
[0053] Organic electroluminescent chromophore 1
[0054] The synthesis method is:
[0055] 1). Synthesis of compound 2 shown in structural formula 2
[0056] Compound 1 shown in 3.9g structural formula 1, 3.5g benzyl bromide, 1.0g 18-crown-6 and 4.1g anhydrous k 2 CO 3 React in 80ml of DMF solution at 60°C under nitrogen atmosphere for 2 hours; after the reaction is complete, add water to the resulting product, extract with dichloromethane and evaporate dichloromethane, anhydrous MgSO 4 dry. After separation by column chromatography (the adsorbent is silica gel), 5.7 g of compound 2 represented by structural formula 2 was obtained;
[0057] 2). Synthesis of compound 3 shown in structural formula 3
[0058] 1.86g of compound 2 shown in structural formula 2...
Embodiment 2
[0064] The organic electroluminescent chromophore 2 with the following structure was synthesized:
[0065]
[0066] Organic electroluminescent chromophore 2
[0067] The synthetic route is as follows:
[0068]
[0069] Organic electroluminescent chromophore 2
[0070] The synthesis method is:
[0071] Basically the same as in Example 1, except that 0.1 g of compound 4 shown in structural formula 4 obtained in step 3 of Example 1 and 0.08 g of SF-TCF were refluxed in 1 ml of absolute ethanol for 0.5 hours; the absolute ethanol was evaporated, and column chromatography ( The adsorbent is silica gel) and separated to obtain 0.1 g of the organic electroluminescent chromophore 2 product shown in the above structural formula. lambda max (CHCl 3 ): 928nm; M + :808; HNMR (CDCl 3 ): δ8.25(br,1H),7.59(d,2H),7.50(d,2H),7.44(d,2H),7.40((d,5H),7.36(t,3H),6.92(d ,1H),6.33(m,4H),6.11(s,1H),5.18(s,2H),3.37(q,4H),2.43(s,2H),2.38(d,2H),1.14(t, 6H), 1.01(d, 6H).
