Abstract

The invention discloses a method for preparing single crystal nanostructure of an organic compound, which comprises the following steps of: (1) disposing a substrate and a quartz boat loaded with an organic compound powder into a quartz tube, connecting the quartz tube with a vacuum system and vacuuming the quartz tube to a pressure 10<-2> to -5 Pa; and (2) heating the quartz boat to the sublimation temperature of the organic compound and heating the substrate to a temperature lower than the sublimation temperature of the organic compound by 130 to 180 DEG C, keeping the vacuum degree in the quartz tube and growing the crystal nanostructure of the organic compound on the substrate. The invention is simple and easy and can obviate the use of a template and a catalyst. The obtained nanostructure has good crystallization, no defect, high purity and better test reproducibility.

Description

technical field [0001] The invention relates to a method for preparing an organic compound single crystal nanostructure. Background technique [0002] Due to their unique properties, nanomaterials not only have huge potential application prospects in electronics, optics, mechanics and other devices, but also have great potential for basic research in the fields of chemistry, physics, electronics, optics, materials science and biological sciences. Profound significance. In recent years, with the development of nanotechnology, the preparation of inorganic and semiconductor nanomaterials has been greatly developed. However, due to the high-temperature instability of organic molecules, the construction of organic compound nanostructures and nanostructure arrays is still a current research topic. difficulty. Recently, it has been reported that copper phthalocyanine and fluorophthalocyanine copper nanobelts and nanowires were prepared by physical vapor deposition of carrier gas,...
