specific Embodiment approach 1

[0019] Embodiment 1: This embodiment is a ferrocene triazole Schiff base derivative, and its general structural formula is: Ar in the general structural formula is

[0020]

[0021] R' is -H, -CH 3 or -CH 2 CH 2 CH 3 .

specific Embodiment approach 2

[0022] Specific embodiment two: This embodiment is the preparation method of ferrocene triazole Schiff base derivative, and is specifically completed according to the following steps:

[0023] 1. Preparation of aryl formate hydrazide: add aryl formate into solvent I, stir until the aryl formate is completely dissolved, and then dropwise into hydrazine hydrate at a rate of 1 mL / min to 2 mL / min under stirring conditions, Hydrazine hydrate is completely added dropwise and heated to reflux temperature, then refluxed for 3h~10h, cooled to room temperature, and then left to stand until no crystals are precipitated, suction filtration to obtain filter cake I, and filter cake I is washed with distilled water for 2~5 times, the washed filter cake I was obtained, and the washed filter cake I was vacuum-dried for 3 h to 8 h at a temperature of 60° C. to obtain an arylformyl hydrazide;

[0024] 2. Preparation of arylformyl hydrazide dithioformate: add the catalyst into solvent II, stir un...

specific Embodiment approach 3

[0032] Embodiment 3: The difference between this embodiment and Embodiment 2 is: the volume ratio of the amount of aryl formate described in step 1 to the volume of solvent I is 1mol:(50-500) mL; step 1 The mol ratio of aryl formate and hydrazine hydrate described in the middle is 1:(1~10); In step 1, the quality of filter cake 1 and the volume ratio of distilled water are 1g:(30~ 50) mL. Others are the same as in the second embodiment.

Abstract

The invention discloses a ferrocene-triazole Schiff base derivative and a preparation method thereof, and relates to a ferrocene derivative and a preparation method thereof. The invention aims to solve the problem that the existing ferrocene and derivatives thereof are poor in electron flow property. The structural general formula of the ferrocene triazole Schiff base derivative is shown in the specification. The preparation method comprises the following steps: 1, preparing aryl formyl hydrazine; 2, preparing aryl formyl hydrazide dithioformate; 3, preparing 3-substituent-4-amino-5-sulfydryl-1,2,4-triazole; and 4, conducting synthesizing to obtain the ferrocene triazole Schiff base derivative. The ferrocene-triazole Schiff base derivative has the advantages that the material has very good electron flowing property and can be used as an electron mediator for a sensor, and the service life of a sensor can be prolonged; and the ferrocene-triazole Schiff base derivative has certain antibacterial activity and can be used for a sensor modification liquid, and when the sensor modification liquid is used for a glucose sensor, the glucose sensor has certain antibacterial activity and pollution resistance. The preparation method is mainly used for preparing the ferrocene-triazole Schiff base derivative.

Description

technical field [0001] The present invention relates to a ferrocene derivative and a preparation method thereof. Background technique [0002] Ferrocene is an organic transition metal compound with aromatic properties and is easily soluble in organic solvents. It does not interact with acids, alkalis and ultraviolet rays. It has stable chemical properties and does not decompose within 400 °C. It has high thermal stability, chemical stability and radiation resistance. Therefore, ferrocene and its derivatives are often used as the composition of various functional materials. Components, such as fuel additives, optical material additives, electrode modifiers, liquid crystal materials, etc., have a wide range of applications in industry, agriculture, medicine, aerospace, energy saving, environmental protection and other industries. However, the electron flow properties of the existing ferrocene and its derivatives are poor. SUMMARY OF THE INVENTION [0003] The purpose of th...
