摘要
The synthesis and characterization of an alternating polyfluorene copolymer with imidazole ligand as the receptor in the pendent side chains were investigated. This system took the advantage of the effective π-conjugation and strong luminescence properties of the polyfluorene. Highly effective transitional metal-sensitive chemosensors were developed through metal ion-coordinating ability of imidazoles and strong luminescence of polyfluorenes. The results show that polymers containing imidazole groups act as promising active materials for application as fluorescent chemosensors.
