Description

technical field

[0001] The invention belongs to the technical field of photoelectric materials, and in particular relates to a fluorene-based ionic water-soluble conjugated polymer, a preparation method thereof, and an application in chemical / biological detection. technical background

[0002] As an excellent electroluminescent material, organic conjugated polymers have been widely used in flexible flat panel displays, polymer batteries, light-emitting batteries, and light-emitting diodes. In recent years, scientists have discovered that the existence of certain trace substances can greatly change the photoelectric properties of conjugated polymers. This change in photoelectric properties makes conjugated polymers a good prospect as a high-sensitivity sensor material.

[0003] Conjugated polymers were initially used in chemical / biological detection, mainly by introducing cyclodextrin or cyclic crown ethers into the side chains of conjugated polymers to detect metal ions. S...
