Paragraph 0150; 0152, (2018/01/09)
The invention belongs to the field of organic semiconductor nanomaterials, and concretely relates to an organic fluorescent sensing material capable of selectively detecting a nerve agent, and a preparation method and application thereof. The invention prepares the organic fluorescent sensing material capable of selectively detecting the nerve agent. A series of P type organic fluorescent sensing materials based on carbazole molecules synthesize to form a structure of a carbazole derivative with different side chains through changing side chains of the carbazole molecules and a polymerization degree thereof, and a one-dimensional organic semiconductor nanowire is obtained through a self-assembly method, namely the organic fluorescent sensing material capable of selectively detecting the nerve agent. The nanowire provided by the invention has the characteristics of large specific surface area, more surface porosity and the like, the nerve agent to be detected is favorably adsorbed and diffused on the surface of the nanowire, and a detection limit is greatly reduced. Therefore, the organic fluorescent sensing material provided by the invention can be used as a fluorescence sensor with an excellent performance capable of recognizing the nerve agent.
