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...

Description

technical field [0001] The invention belongs to the field of organic nonlinear optical materials, in particular to a sandwich-type phthalocyanine rare earth complex with two-photon absorption properties and a preparation method thereof. Background technique [0002] Two-photon absorption is a nonlinear optical phenomenon, which is a process in which a medium absorbs two photons simultaneously through a virtual molecule under strong light excitation, and transitions from the ground state to an excited state with twice the energy of the photon. Two-photon absorbing materials have important application prospects in many modern high-tech fields such as three-dimensional microfabrication, two-photon dynamic therapy, two-photon optical clipping, three-dimensional optical data storage, and fluorescence microscopy imaging. The development and research of materials has developed into one of the most active research fields in the world. Compared with other two-photon absorbing materi...
