AI Technical Summary
Simple all-aromatic polyimides (Ar-PIs) do not have fluorescence and are difficult to form films, so they cannot be directly applied to light-emitting devices.
By introducing anthracene groups, an anthracene fluorescent polymer is prepared. A specific chemical reaction step is used to react 9,10-dibromoanthracene with 3-nitrophenylene boric acid and other raw materials under certain conditions to form a fluorescent polymer, and a film is formed in an organic solvent through a two-step method.
The obtained anthracene-based fluorescent polymer has good fluorescence and solubility, and can directly form films in a variety of organic solvents, and is used in light-emitting devices such as fluorescent probes and fluorescent sensing films, which improves the application potential of polyimide.
