Embodiment 1

[0028] Add 6.97 mg of methoxydimethylaminoamine styryl phenyl ketone to 4 mL of dichloromethane and sonicate for 3 min to obtain a stock solution of methoxydimethylaminoamine styryl phenyl ketone dichloromethane. Take 1 mL of the stock solution and add it to 1 mL of ethanol, shake well, and then drop it on the substrate (such as silicon wafer, glass wafer or quartz wafer). After the organic solvent is evaporated to dryness, organic nanowires with a strong deep red color are obtained. By powder X-ray diffraction (XRD, Figure 4 ), scanning electron microscopy (SEM, Figure 5 ), transmission electron microscopy (TEM), and selected electron diffraction (SAED) ( Figure 6 ) test means to characterize the organic eutectic micro-crystals.

Embodiment 2

[0030] Add 6.35 mg of dimethylaniline styryl phenyl ketone to 4 mL of dichloromethane and sonicate for 3 min to obtain a stock solution of dimethyl aniline styryl phenyl ketone in dichloromethane. Take 1 mL of the stock solution and add it to 5 mL of ethanol, shake well, and then drop it on the substrate. After the organic solvent evaporates to dryness, high-quality organic nanowires with uniform morphology are obtained. scanning electron microscope (SEM, Figure 7 ) test means to characterize organic micro-crystals.

Embodiment 3

[0032] Add 6.94 mg of methoxydimethylaminoamine naphthalene vinyl phenyl ketone to 4 mL of dichloromethane and sonicate for 3 min to obtain a stock solution of methoxy dimethylaminoamine naphthyl vinyl phenyl ketone dichloromethane. Take 1 mL of the stock solution and add it to 10 mL of ethanol, shake well, and then drop it on the substrate. After the organic solvent evaporates to dryness, high-quality organic nanowires with uniform morphology are obtained. scanning electron microscope (SEM, Figure 8 ) test means to characterize organic micro-crystals.

Abstract

The invention provides a synergistic and controllable method for preparing nanowires of organic semiconductor materials. The preparation steps are as follows: Accurately weigh organic semiconductor molecules, add a good organic solvent and ultrasonically obtain organic semiconductor molecule organic solvent stock solution; Add the organic semiconductor molecule organic solvent stock solution to the poor organic solvent at room temperature, shake well, let it stand for a period of time, drop it on the substrate, and obtain the organic single crystal nanowire structure material after the organic solvent evaporates to dryness. The invention provides a new way for the preparation of simple, quick, controllable and uniform size organic single crystal nanowires, and has very high academic value and application prospect in the development of nanoscale optoelectronic devices.

Description

technical field [0001] The invention relates to a method for preparing an organic semiconductor nanowire material, in particular to a method for synergistically controlling the preparation of an organic semiconductor material nanowire. Background technique [0002] With the development of science and technology, the size of electronic devices is required to be further miniaturized, and the integration level of integrated circuits is further improved. However, traditional crafts encounter increasingly severe challenges in this respect. In the past two decades, one-dimensional nanowires, one of the most promising applications in nanoscale optoelectronic devices, have attracted more and more attention due to their unique physical and chemical properties. Because organic molecular materials are light in weight, cheap, flexible and tailorable, and have excellent optoelectronic properties and flexibility, organic semiconductor materials have certain advantages in optoelectronic d...
