Embodiment 1
[0069] Synthesis of ligand A-1:
[0070]
[0071] 1) Prepare 30 mL of anhydrous tetrahydrofuran solution containing 1.0 mmol of compound 2 (diethyl 2,2'-bipyridine-4,4'-dimethyl phosphate, Nanjing Kangran Pharmaceutical Technology Co., Ltd.) and 2.4mmol potassium tert-butoxide, weigh solution 1;
[0072] 2) Prepare 20 mL of a THF solution containing 2.4 mmol of compound 1 (N-ethyl substituted carbazole-3-carbaldehyde, Bailingwei Chemical Technology Co., Ltd.), and call it solution 2;
[0073] 3) In a reaction vessel protected by argon at 25°C, slowly drop solution 2 into solution 1, and react at 25°C for 24 hours after the addition is complete. After the reaction, THF was removed, HCl aqueous solution (5M, 40 mL) was added, and then extracted three times with 60 mL chloroform. The organic phase was collected and washed with 3M HCl aqueous solution. The organic phases were combined and used anhydrous MgSO 4 After drying, the solvent was removed by rotary evaporation to obtain a black...
Embodiment 2
[0080] Synthesis of ligand A-2:
[0081]
[0082] The organic ligand was prepared by the same method as in Example 1. The difference is that the above compound 7 is used instead of the compound 1 in Example 1 as a raw material to synthesize ligand A-2. Compound 7 was synthesized by reference (Ahn, T.; Song, S.Y.; Shim, H.K. Macromolecules 2000, 33, 6764.).
[0083] Synthetic route of metal organic dye I-B:
[0084]
[0085] Dye formula I-B
[0086] The organometallic dye was prepared by the same method as in Example 1. The difference is that the above ligand A-2 is used instead of the ligand A-1 in Example 1 as the raw material to synthesize dye I-B.
[0087] Dye I-B 1 H NMR data: 1 H NMR(CD 3 OD): δ9.50(d, 1H), 9.03(d, 1H), 9.00(s, 1H), 8.89(s, 1H), 8.87(s, 1H), 8.83(s, 1H), 8.23~7.12 (m, 24H), 4.42 (m, 4H), 1.98 (m, 2H), 1.29 (m, 16H), 0.87 (m, 12H).
Embodiment 3
[0089] Synthesis of metal organic dye II-A
[0090]
[0091] Dye formula II-A
[0092] Using the same ligand A-1 as in Example 1, compound 8 was synthesized by reference (Gillaizeau-Gauthier, I.; Odobel, F.; Alebbi, M.; Argazzi, R.; Costa, E.; Bignozzi, CA; Qu, P.; Meyer, GJ Inorg. Chem. 2001, 40, 6073.). The synthesis of dye II-A adopts the same method as in Example 1, and only needs to replace monomer 4 with monomer 8.
[0093] Dye II-A 1 H NMR data: 1 H NMR(CD 3 OD): δ9.50(d, 1H), 9.08(d, 1H), 8.92(s, 1H), 8.88(s, 1H), 8.86(s, 1H), 8.80(s, 1H), 8.25~7.14 (m, 24H), 4.40 (m, 4H), 1.49 (m, 6H).
