Embodiment 1
[0019] (1) 6.51g3.6-dichlorophthalic anhydride, 1.10g pyromellitic anhydride, 1.98gFeCl 2 4H 2 O, 9.47g of urea and 0.25g of ammonium molybdate were mixed evenly and finely ground. After the mixture was heated at 190°C for 1 hour, the reaction was continued at 250°C for 2 hours. The product was successively washed with ammonia solution, dilute hydrochloric acid and water, and then dried. The crude product was extracted and washed with ethanol and tetrahydrofuran until it was colorless, and further purified by silica gel chromatography (N,N-dimethylformamide as the eluent) to obtain the dark blue target product dodecachloro-substituted dinuclear phthalocyanine iron (II ). UV-Vis (DMSO as a solution): λ max 662nm. 1 HNMR (DSMO-d 8 ): δ11.3~11.8 (2H, aroma). Elemental Analysis: Calculated for C, 50.07; H, 13.58; N, 15.10; Fe, 7.53. Found C, 50.01; H, 13.55; N, 15.12; Fe, 7.60. Mass Spectrum (LDI-TOF-MS) Found (Calcd): M / e=1483.6 (1483.1) [M + ]
Embodiment 2
[0021] 6.60g tetrafluorophthalic anhydride, 1.10g pyromellitic anhydride, 1.98g FeCl 2 4H 2 O, 9.47g of urea and 0.25g of ammonium molybdate were mixed evenly and finely ground. After the mixture was heated at 110°C for 1.5h, the reaction was continued at 220°C for 3h. The product was washed with ammonia solution, dilute hydrochloric acid and water in turn, and then dried. The crude product was extracted and washed with ethanol and tetrahydrofuran until it was colorless, and further purified by silica gel chromatography (N,N-dimethylformamide as the eluent) to obtain the dark blue target product Tetrafluoro-substituted dinuclear iron phthalocyanine ( II). UV-Vis (DMSO as a solution): λ max 651nm. 1 HNMR (DSMO-d 8 ): δ 10.5 to 10.8 (2H, aroma). Elemental analysis: calculated value C: 49.06, H: 13.31, N: 14.30, Fe: 7.37; found value C: 49.02, H: 13.40, N: 14.26, Fe: 7.42. Mass Spectrum (LDI-TOF-MS) Found (Calcd): M / e=1514.2 (1513.6) [M + ]
