Embodiment Construction

[0037] The preparation process of the zinc halide terpyridine coordination polymer in the present embodiment is as follows:

[0038] 1. Synthesis of (γ; γ) triphenylamine terpyridine (tpatpy) ligand

[0039] Add 2.73g (10.0mmol) triphenylamine monoaldehyde, 2.67g (22.0mmol) 4-acetylpyridine and 50mL absolute ethanol into a 150mL single-necked round-bottomed flask, stir well, and add 1.71ml dissolved in 3mL deionized water dropwise. g (22.0mmol) KOH aqueous solution, stirred at room temperature, and continued to stir for 30min after the reaction solution turned brownish red, then added 30mL of ammonia water with a mass concentration of 25-28%, refluxed at 85°C for 24h, cooled to room temperature after the reaction, and filtered with suction Dry it and separate it by column chromatography (eluent: petroleum ether: ethyl acetate = 5:1, v / v) to obtain 2.70 g of a light yellow sample with a yield of 56.72%.

Abstract

The invention discloses a zinc halide terpyridine coordination polymer multifunctional material and a preparation method thereof. The structural formula of the zinc halide terpyridine coordination polymer multifunctional material is shown in the specification, wherein X refers to Cl, Br or I. A zinc halide terpyridine coordination polymer [Zn(tpatpy)X2]n prepared through the method is a multifunctional material integrating the frequency-doubled effect, the two-photon absorption effect and the ferroelectric effect, and has wide application prospects in the high-tech technical field of nonlinear optics. Compared with a traditional second-order linear optical material of urea, the n-times frequency effect of the coordination polymer [Zn(tpatpy)Cl2]n prepared through the method is higher and is 22 times that of the urea.

Description

1. Technical field [0001] The invention relates to a ferroelectric composite material and a preparation method thereof, in particular to a zinc halide terpyridine coordination polymer multifunctional material and a preparation method thereof, belonging to the field of functional materials. 2. Background technology [0002] With the progress of society and the development of science and technology, single-functional materials can no longer meet the needs of practical applications. The development of multi-functional materials is a new challenge for materials scientists. Coordination polymer materials have the advantages of both inorganic materials and organic materials, and have the advantages of exchangeable central ions, designable ligands, and diversity of crystal structures. In recent years, they have been widely studied at home and abroad. Coordination polymer materials with single functions such as electricity and magnetism have been reported successively. Using the co...
