Embodiment 1

[0031] Embodiment 1, the preparation of the DMQA one-dimensional organic nanomaterials of concentric circular arrangement

[0032] The organic matter that present embodiment uses is N, N'-dimethylquinacridone (DMQA), and its structure is as shown in formula (1), and its synthetic method reference (Liu Bo, Li Wei, Deng Deng, Zhang Yuxiang N, N Synthesis of '-Dimethylquinacridone. Applied Chemical Industry, 2003, 32(5): 63~64).

[0033] The specific preparation method is as follows: under the protection of nitrogen, add 200 mg of quinacridone, 200 mg of tetrabutylammonium bromide, and 20 ml of dioxane into a 250 ml three-necked bottle, weigh 700 mg of 60% sodium hydride, and use industrial petroleum ether and dioxane The six rings were washed three times, mixed with 2ml of dioxane, and added to the three-necked bottle. Raise the temperature and reflux for 2 hours, add dropwise 3ml of dimethyl sulfate, react for 2 hours, and recover dioxane. 10ml of methanol was added dropwise,...

Embodiment 2

[0041] Embodiment 2, the preparation of the DMQA organic nanowire film of alignment

[0042] The preparation method is basically the same as in Example 1, the difference is that the CH of 0.05mmol / L DMQA 3 Add the Cl solution into the gap between the plano-convex lens and the glass slide, and put the device in a closed container at the same time, so that the solvent evaporates slowly. In this case, a thin film of one-dimensional organic nanomaterials with alignment can be obtained, such as image 3 shown.

Embodiment 3

[0043] Embodiment 3, the preparation of the PTCDI one-dimensional organic nanomaterial pattern of the alkyl substitution of concentric circle arrangement

[0044] The preparation method is basically the same as in Example 1, except that the organic compound used in this example is perylenetetracarboxylic diimide (PTCDI) substituted by an alkyl group with 3-8 carbons, and its structure is as shown in formula (2) shown. The concentration of the alkyl-substituted PTCDI in the organic compound solution used was 0.10 mmol / L.

[0045] The synthesis method of this compound refers to (Zhang Wenguan, Zhao Shengmin, Crystal Form and Properties of n-Butylperylenetetracarboxylic Diimide. Spectroscopy and Spectral Analysis, 2006, 26(2): 302~305), and the specific preparation The method is as follows: 615 mg of perylene anhydride, 800 mL of n-pentylamine, 10 mL of quinoline, 85 mg of zinc oxide and 0.25 mL of acetic acid are reacted at a temperature of 210 ° C, and the reaction time is 8 h...

Abstract

The invention discloses a method for arranging one-dimensional organic nano materials in an orientating and patterning manner, which comprises the steps of: 1, constructing a volatilizing device, wherein the volatilizing device comprises a planoconvex spotlight and a substrate, the convex surface of the planoconvex spotlight faces downwards and is horizontally placed above the substrate and in contact with the substrate; and 2, adding an organic compound solution in a gap between the planoconvex spotlight and the substrate of the volatilizing device in the step 1, standing the device to ensure that the solvent in the organic compound solution in the gap is volatilized, and after the solvent is completely volatilized, obtaining a concentric circle shaped pattern formed by the one-dimensional organic nano materials or an organic nano wire film with orientated arrangement on the substrate. The method is simple and practicable, can realize the self-assembly, orientated arrangement and patterning of the one-dimensional organic nano materials by one step, and is suitable for the preparation and the orientated arrangement of the one-dimensional organic nano materials of various organic micromolecular compounds.

Description

technical field [0001] The invention relates to a method for aligning and patterning one-dimensional organic nanomaterials. Background technique [0002] Organic semiconductor nanostructures may find a place in future microelectronic devices such as displays and sensor arrays due to their excellent optoelectronic properties. However, due to the difficulties in the preparation of devices, more research is currently focused on the electrical properties of single nanostructures or randomly stacked thin film structures. The disadvantages of these devices are obvious: the device performance is difficult to improve, and the repeatability is poor; at the same time, the disordered thin film structure is not conducive to reducing material consumption. Therefore, it is very urgent to develop a simple and effective method to align and pattern a large number of one-dimensional organic small molecule semiconductor nanomaterials. [0003] The reported methods for one-dimensional organic...
