Embodiment 1

[0010] Embodiment 1: (BW 12 / BBY) n Preparation of multilayer organic-inorganic thin films

[0011] 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.

[0012] 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.

[0013] Then the PEI cationized substrates were alternately immersed in 4.0×10 -2 M's BW 12 solution and 1.0 x 10 -3 In the M BBY solution, place it separately for 20min, wash it with distilled water after each immersion step, and dry i...

Embodiment 2

[0016] Embodiment 2: ([Co 4 II (H 2 O) 2 (PW 9 o 34 ) 2 ] 10- / BBY) n Preparation of multilayer organic-inorganic thin films

[0017] 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.

[0018] The UV-Vis spectrum shows that the prepared film is [Co 4 II (H 2 O) 2 (PW 9 o 34 ) 2 ] 10- The absorbance of / BBY increases linearly with the increase of the number of layers, indicating that the prepared film has good uniform growth. AFM characterization results show that the film surface is very uniform, ([Co 4 II (H 2 O) 2 (PW 9 o 34 ) 2 ] 10- / BBY) 4 and ([Co 4 II(H 2 O) 2 (PW 9 o 34 ) 2 ] 10- / BBY) 4 -[Co 4 II (H 2 O) 2 (PW 9 o 34 ) 2 ] 10- The surface roughness (RMS) of the film is 0.971nm, 1.694nm (1.0×1.0μm 2 . Film ([Co 4 II (H 2 O) 2 (PW 9 o 34 ) 2 ] 10- / BBY) 4 Surface roughness ratio ([Co ...

Embodiment 3

[0019] Embodiment 3: (BW 12 / AzA) n Preparation of multilayer organic-inorganic thin films

[0020] Synthesis steps and testing steps refer to Example 1. Among them, the immersion organic dye of the substrate adopts 0.5×10 -3 M AzA solution.

[0021] The UV-Vis spectrum shows that the prepared film has BW at wavelengths of 250nm, 285nm and 594nm 12 The absorbance of / AzA increases linearly with the increase of the number of layers, indicating that the prepared film has good uniform growth.

[0022]The atomic force microscope characterization results of the film show that the film surface is very uniform, (BW 12 / AzA) 4 and (BW 12 / AzA) 4 -BW 12 The surface roughness (RMS) of the films were 1.324nm and 1.715nm, respectively. Film (BW 12 / AzA) 4 -BW 12 Surface roughness ratio (BW 12 / AzA) 4 Large, indicating the successful preparation of the film.

Abstract

An organic-inorganic membrane is self-assembly by organic dye and polyoxometallate and relates to an organic-inorganic membrane and the manufacturing method of the same. The membrane is manufactured by XW12(x=B, Si, P)or[M4II(H20)(PW9O34)2]10-(M=Co, Cu, Zn, Mn)and organic dye of Bismarck Brown Y, Azure A and Basic Blue3 by means of a layer upon layer self-assembly method. The membrane has the abundant chemical properties of polyoxometallate and has the properties of organic dye, and has potential application prospect in the aspects of chemical modification electrode and optical material.

Description

technical field [0001] The invention relates to an organic-inorganic composite film, in particular to an organic-inorganic composite film self-assembled by organic dyes and polyoxometalates. Background technique [0002] With the rapid development of electronics and information science, people's research on material science has developed rapidly, which also requires devices to be miniaturized, multifunctional, and integrated. However, materials prepared from a single species composition are difficult to meet multiple needs at the same time. The organic-inorganic composite film combines organic matter and inorganic matter at the molecular level, so that the material has both the flexibility of organic matter and the rigidity of inorganic matter. Currently, organic-inorganic composite membranes have been extensively studied due to their potential applications in industry. Organic dye molecules have potential technical applications in nonlinear optics, holography, data storag...
