Abstract

The invention discloses a preparation method of a ferrocene-perylene diimide-based functional material nanowire, and an application of the nanowire. The preparation method of the ferrocene-perylene diimide-based functional material nanowire comprises the following steps: dissolving a functional material in a dichloromethane solution to prepare a 1*10<-3>mol / L concentrated solution for later use, and taking 1mL of the standby concentrated solution in a test tube, rapidly adding 10mL of an n-hexane solution to the test tube, and allowing the obtained solution mixture to stand for 1-10h to form the nanowire at the bottom of the test tube. The nanowire can be used for constructing micro-nano devices, and the micro-nano devices have a stable electrical bistability, can be used for high-density information storage and molecular switch, and can be widely applied. A new ideal and a new way are provided for the design of novel functional storage mediums and the preparation of molecular electric devices, and good economic and social benefits are possessed.
