Embodiment 1

[0009] Embodiment 1: (BW 12 / pAC4) n Preparation of multilayer organic-inorganic thin films

[0010] First, clean the quartz sheet: put the quartz glass sheet in 98% H 2 SO 4 with 30%H 2 o 2 (7:3v / v) dipping treatment at 80°C for 40min, take it out and wash it with distilled water; then immerse in H 2 O:H 2 o 2 : NH 3 =5:1:1 (v / v / v) dipping treatment at 80°C for 20 minutes, take it out, wash it with distilled water, and dry it with nitrogen to obtain a film-forming substrate for use.

[0011] Then perform PEI cationization on the substrate: immerse the substrate after the above-mentioned treatment procedure in 10 mg / mL polyethyleneimine PEI solution for 20 minutes, take it out, wash it with distilled water, and dry it with nitrogen.

[0012] Then the PEI cationized substrates were alternately immersed in 4.0×10 -2 M's BW 12 solution and 2.0 x 10 -3 In the MpAC4 solution (through hydrochloric acid cationization), place respectively 20min, wash with distilled water a...

Embodiment 2

[0014] Embodiment 2: ([Co 4 II (H 2 O) 2 (PW 9 o 34 ) 2 ] 10- / pAC4) n Preparation of multilayer organic-inorganic thin films

[0015] Synthesis steps and testing steps refer to Example 1. The immersion solution of PEI cationized substrate adopts 5.0×10 -3 M's [Co 4 II (H 2 O) 2 (PW 9 o 34 ) 2 ] 10- solution.

[0016] The UV-Vis spectrum shows that the prepared film is at the wavelength of 250nm and 300nm [Co 4 II (H 2 O) 2 (PW 9 o 34 ) 2 ] 10- The absorbance of / pAC4 increases linearly with the increase of the number of layers, indicating that the prepared film has good uniform growth.

Embodiment 3

[0017] Embodiment 3: (BW 12 / pAC4) n Characterization of Electrochemical Behavior of Multilayer Organic-Inorganic Thin Films

[0018] The electrochemical behavior was carried out using an Epsilon type electrochemical workstation produced by BAS Company of the United States. A glassy carbon electrode (3mm) was used as the working electrode, a platinum wire electrode was used as the counter electrode, and Ag / AgCl / KCl (3M) was used as the reference electrode. The supporting electrolyte is 0.1M NaCl solution. The electrochemical method was cyclic voltammetry.

[0019] The working electrode modification steps are as follows: first, the glassy carbon electrode (3 mm in diameter) was pretreated with 1.0, 0.3 and 0.05 μm α-Al 2 o 3 The polishing powder is polished separately, cleaned with acetone and distilled water ultrasonically after each polishing, and finally dried with nitrogen; then immersed in 10mg / mL polyethyleneimine PEI solution for 20min, washed with distilled water a...

Abstract

The polyoxometallate and calixarene amide self-assembled organic-inorganic composite film relates to an organic-inorganic film and its preparation method. Said film is made up by adopting WX12 (X=B, Si and P) or [M4 11 (H2O)2(PW9O34)2]10- (M=Co, Cu, Zn and Mn) and P-tetraamino-calix [4] arene through a layer-by-layer self-assembly process. Said film possesses rich electrochemical performance of polyoxometallate and performance of calixarene macrocyclic compound, so that it has extensive application in the chemical modified electrode and metal ion sensor material field.

Description

technical field [0001] The invention relates to an organic-inorganic composite film, in particular to an organic-inorganic film self-assembled by polyoxometalate and amidated calixarene. Background technique [0002] With the rapid development of electronics and information science, people have put forward higher and higher requirements for materials, requiring miniaturization, multi-function, and integration of devices. However, materials prepared from a single species composition are difficult to meet multiple needs at the same time. The organic-inorganic composite membrane combines organic matter and inorganic matter at the molecular level, so that the material has both the characteristics of organic matter and the performance of inorganic matter. Polyoxometalates (POMs), as a typical class of inorganic metal oxygen cluster compounds, have rich structural, chemical and physical properties, so they have important theoretical research in the fields of catalysis, medicine a...
