Embodiment Construction

[0039] 1. Synthesis of Intermediate 1

[0040] In a 500mL round bottom flask, add 12.02g (0.1mol) of diethylene glycol monomethyl ether and dissolve it in 90mL of dichloromethane, add 0.32g catalyst 4-butylammonium bromide and 100mL of a mass concentration of 30% NaOH aqueous solution, Stir and mix evenly, dissolve 32.41g (0.17mol) of 4-methylbenzenesulfonyl chloride in 100mL of dichloromethane and add it dropwise to the reaction system. Once, dry over anhydrous magnesium sulfate for 8-12 hours, take the filtrate after suction filtration, remove the solvent by rotary evaporation, and refrigerate at -2~-6°C for 8-12 hours to obtain the intermediate 1-p-toluenesulfonyl polyethylene glycol 24.4 g of monomethyl ether is a white ice-like solid, and the yield is 89%.

Abstract

The invention discloses a nickel complex optical amplitude limiting material and a preparation method thereof. The structural formula of the nickel complex optical amplitude limiting material is shown in the picture in the instruction. A nickel complex (NiL2) has good optical amplitude limiting effect. Compared with that in a document report, the nickel complex has a low amplitude limiting threshold value being 0.36J / cm<2> and a high damage threshold value being 0.98J / cm<2>. By utilizing a femtosecond laser device, under the condition of 700nm wavelength, the optical amplitude limiting effect of the nickel complex is measured, and compared with that in the document report, the nickel complex is low in response time and wide in amplitude limiting wave band and reaches the red light range.

Description

1. Technical field [0001] The invention relates to an optical limiting material and a preparation method thereof, in particular to a nickel complex with good optical limiting effect and a preparation method thereof. 2. Background technology [0002] Since Gordon et al. (Appl. Phys., 1965, 36, 3-8) first reported the phenomenon of optical clipping in 1964, there have been many laser protection methods developed based on the theory of nonlinear optics, and their application ranges throughout industry, All aspects of agriculture, national defense and science and technology. Especially in the military field, the protection needs of human eyes, photoelectric sensor devices and optical systems, as well as the protection needs of international terrorist activities against laser weapons (laserweapons), optical limiting materials have become a research hotspot at home and abroad because of their important research value. . [0003] The development of research on optical limiting ma...
