Abstract

The invention relates to a method for preparing arrayed organic nanoparticles. The method comprises: adopting a AgClO4 and I2 oxidation method or a FeCl3 oxidation method to prepare cation radical solution of organic molecules; dipping arrayed metal electrode substrates in the solution; allowing cations to be subjected to replacement reaction with arrayed metal on the electrode substrates; and obtaining the arrayed organic nanoparticles. The method provided by the method is simple, practicable and capable of preparing the arrayed organic nanoparticles in large area.

Description

technical field [0001] The invention relates to a method for preparing arrayed organic nanoparticles. Background technique [0002] In the past few decades, organic semiconducting molecules have attracted extensive attention due to their low cost and ease of large-scale production. Among them, nanostructured organic semiconductors have become important research objects in the fields of displays, integrated circuits, solar cells, sensors, and information storage due to their remarkable electrical properties. [0003] At present, there are many methods for preparing patterned arrayed organic nanodevices, such as physical vapor transport method, liquid phase impregnation method, organometallic vapor phase / liquid phase coordination reaction method, etc. Among them, the physical vapor transport method needs to modify the substrate, the process is complicated, the cost is high, and it is not suitable for large-scale production. The liquid-phase impregnation method is only suitab...
