Abstract:

A facile synthetic route for conjugated polymer PPESO3 was proposed, through which not only the procedure was simplified, but also the dealkylation by BBr3 was avoided, and therefore, the preparing difficulty and danger were greatly reduced, which was obviously beneficial to the preparation and application of PPESO3. At the same time, the interactions between PPESO3 and nonionic surfactant(PVP) were investigated. The results indicate that the aggregation of polymer backbone was effectively broken up and the steady complexes consisted of PPESO3 and PVP were formed which would contribute to the preparation of highly sensitive bio-sensors due to the affinity of PVP to biological macromolecules.

Key words: Conjugated polymers; PPESO3; Sensors; Nonionic surfactant; PVP
