Embodiment 1

[0027] In this example, oxalic acid (3.1mmol, 0.39g), zinc oxide (2mmol, 0.16g), TPT (0.12mmol, 0.036g), phosphoric acid (0.2mL) and DMF (0.12mL) were sequentially added to polytetrafluoroethylene as a lining Sealed in a stainless steel reaction kettle, and crystallized in an oven at 145°C for 7 days. After the reaction was completed, the stainless steel reaction kettle was taken out and cooled naturally at room temperature, and the crystals generated in the stainless steel reaction kettle were removed and washed repeatedly with deionized water for 5 times. , dried at room temperature to obtain colorless (or light purple) massive crystals, the prepared crystals were subjected to single crystal diffraction, and the data analysis showed that the obtained compounds had a columnar structure, in which phosphoric acid and oxalic acid chelated-bridged Zn 2+ A two-dimensional hybrid layer is formed, and the TPT ligand passes through the interlayer Zn 2+ Coordinated, pillared 2D layer ...

Embodiment 2

[0029] In this example, oxalic acid (3.1mmol, 0.39g), zinc oxide (2mmol, 0.16g), TPT (0.12mmol, 0.036g), phosphoric acid (0.2mL) and DMAc (0.12mL) were sequentially added to polytetrafluoroethylene as a lining Sealed in a stainless steel reaction kettle, crystallized in an oven at 145° C. for 7 days and after the reaction was completed, passed through the cooling, washing and drying methods as in Example 1. The characteristics and results of the target product obtained were the same as in Example 1.

Embodiment 3

[0031] In this example, oxalic acid (3.1mmol, 0.39g), zinc oxide (2mmol, 0.16g), TPT (0.12mmol, 0.036g), phosphoric acid (0.2mL) and DMAc (0.12mL) were sequentially added to polytetrafluoroethylene as a lining Sealed in a stainless steel reaction kettle, and crystallized in an oven at 145°C for 8 days. After the reaction was completed, through the cooling, washing and drying methods as in Example 1, the characterization and results of the target product obtained were the same as in Example 1.

Abstract

The invention belongs to the technical field of synthesis of organic-inorganic hybrid materials and relates to an electron transfer type hybrid photochromic material and a preparation method thereof.The method comprises the following steps: uniformly mixing oxalic acid, a metal source, TPT, a phosphorus source and DMF or DMAc to obtain a mixture, loading the mixture to a stainless steel high-pressure reaction container provided with a polytetrafluoroethylene reactor and crystallizing the mixture at 145 DEG C for 7-8 days to obtain blocky colorless or grey violet crystals with good crystallinity; performing deionized water washing and suction filtration on the crystals sequentially, and performing drying at room temperature to obtain the electron transfer type hybrid photochromic material.The prepared material is novel in structure, the preparation process is simple and convenient to operate, and reference is provided for design synthesis and application research of the electron transfer type hybrid photochromic material.

Description

Technical field: [0001] The invention belongs to the technical field of synthesis of organic-inorganic hybrid materials, and relates to an electron-transfer hybrid photochromic material guided by a column layer structure strategy and a preparation method thereof. Background technique: [0002] Photochromic compounds refer to certain compounds that undergo color changes under the action of light of a certain wavelength and intensity, and this change is generally reversible. Due to the characteristics of reversible switching between two different stable states, this class Materials have been used in many fields, such as ink, cosmetics, automobiles, etc., and have shown broad application prospects in molecular switches, radiation detection, and biological imaging. According to the properties of materials, photochromic materials are mainly divided into three categories: inorganic photochromic materials, organic photochromic materials, and inorganic-organic hybrid photochromic ma...
