Embodiment 1
[0027] Weigh 0.46g of yttrium acetylacetonate hydrate and 0.51g of o-dicyanobenzene into a sealed reactor, add 5mL of n-pentanol and 12 drops of catalyst DBU, and heat and stir at 100°C for 2 hours under nitrogen protection. After the product is cooled, the n-pentanol is distilled off. Dissolve the solid product in a small amount of chloroform, purify it with a chromatographic column, and shower it with a chloroform-methanol solution (chloroform:methanol=95:5) to obtain a single-layer yttrium phthalocyanine complex. After repeated purification and recrystallization with chloroform and n-hexane, the pure product was obtained with a yield of 45%.
[0028] Add 0.15 g of monolayer yttrium phthalocyanine complex obtained in the above steps, 0.26 g of 4,5-dioctyloxy-o-dicyanobenzene and catalyst DBU10 dropwise into 5 mL of n-pentanol, and heat to React at 150°C for 10 hours. After the product is cooled, add 50 mL of n-hexane to the reactor for recrystallization, filter the solid p...
Embodiment 2
[0030] Weigh 1 g of yttrium acetylacetonate hydrate and 1.2 g of o-dicyanobenzene into a sealed reactor, add 10 mL of n-pentanol and 12 drops of catalyst DBU, and heat and stir at 100°C for 2 hours under nitrogen protection. After the product is cooled, the n-pentanol is distilled off. Dissolve the solid product in a small amount of chloroform, purify it with a chromatographic column, and shower it with a chloroform-methanol solution (chloroform:methanol=95:5) to obtain a single-layer yttrium phthalocyanine complex. After repeated purification and recrystallization with chloroform and n-hexane, the pure product was obtained with a yield of 35%.
[0031] Add 0.5 g of monolayer phthalocyanine yttrium complex obtained in the above steps, 0.9 g of 4,5-dioctyloxy-o-dicyanobenzene and catalyst DBU10 dropwise into 10 mL of n-pentanol, and heat to React at 150°C for 10 hours. After the product is cooled, add 50 mL of n-hexane to the reactor for recrystallization, filter the solid pr...
Embodiment 3
[0033] Weigh 0.46g of yttrium acetylacetonate hydrate and 0.51g of o-dicyanobenzene into a sealed reactor, add 5mL of n-pentanol and 12 drops of catalyst DBU, and heat and stir at 100°C for 4 hours under nitrogen protection. After the product is cooled, the n-pentanol is distilled off. Dissolve the solid product in a small amount of chloroform, purify it with a chromatographic column, and shower it with a chloroform-methanol solution (chloroform:methanol=95:5) to obtain a single-layer yttrium phthalocyanine complex. After repeated purification and recrystallization with chloroform and n-hexane, the pure product was obtained with a yield of 47%.
[0034] Add 0.15 g of monolayer yttrium phthalocyanine complex obtained in the above steps, 0.26 g of 4,5-dioctyloxy-o-dicyanobenzene and catalyst DBU10 dropwise into 5 mL of n-pentanol, and heat to React at 150°C for 14 hours. After the product is cooled, add 50 mL of n-hexane to the reactor for recrystallization, filter the solid p...
