Embodiment 1

[0014] A preparation method of cadmium metal organic complex, comprising the following steps:

[0015] Mix 0.2 mmol of 6-aminonicotinic acid with 0.1 mmol of Cd(NO 3 ) 2 4H 2 Add the mixture of O to 10ml of distilled water, add NaOH solution dropwise to adjust the pH to about 2, stir well and place it in a stainless steel reaction kettle lined with polytetrafluoroethylene, react under 433K for 3 days, then cool slowly Colorless flaky crystals are obtained at room temperature, which is the cadmium metal-organic complex.

Embodiment 2

[0017] Mix 0.2 mmol of 6-aminonicotinic acid with 0.1 mmol of Cd(NO 3 ) 2 4H 2 Add the mixture of O to 10ml of distilled water, add NaOH solution dropwise to adjust the pH to about 3, stir well and place it in a stainless steel reaction kettle lined with polytetrafluoroethylene, react under 433K for 3 days, then cool slowly to room temperature to obtain the target product.

Embodiment 3

[0019] Mix 0.2 mmol of 6-aminonicotinic acid with 0.1 mmol of Cd(NO 3 ) 2 4H 2 Add the mixture of O to 6ml of distilled water, add NaOH solution dropwise to adjust the pH to about 4, stir well and place it in a stainless steel reaction kettle lined with polytetrafluoroethylene, react under 433K for 3 days, then cool slowly to room temperature to obtain the target product.

Abstract

The invention discloses a preparation method of a cadmium metal organic complex. The preparation method is characterized by comprising the steps: adding a mixture of 0.2mmol of 6-aminonicotinic acid and 0.1mmol of Cd(NO3)2.4H2O into 10ml of distilled water, adding a NaOH solution dropwise until a pH value is 2-4, fully mixing, putting a mixture into a stainless steel reaction kettle with polytetrafluoroethylene as a liner, carrying out hydrothermal reaction with 2.9-3.2d under the condition of 430-440K, and slowly cooling to the room temperature to obtain a colorless tabular crystal, i.e., the cadmium metal organic complex. The cadmium metal organic complex has the fluorescence and can be applied to fluorescent materials.

Description

technical field [0001] The invention mainly relates to the field of materials, in particular to a preparation method of a cadmium metal organic complex. Background technique [0002] Coordination polymers are compounds formed by metal ions as connection points and bridging ligands through coordination bonds, and their dimensions are zero-dimensional, one-dimensional, two-dimensional and three-dimensional. Metal-organic coordination polymers have the properties of both inorganic metal ions and organic ligands, and have attracted extensive research interest due to their potential applications in fluorescence, magnetic materials, gas adsorption and separation, antibacterial and nonlinear optical materials. . In 1995, the O.M. Yaghi research group first proposed the concept of "metal-organic frameworks", and published a report on the synthesis of MOF-5 in 1999. In the past ten years, researchers have used different organic ligands to interact with various metal ions to pre...
