中文摘要	herein, homogenously partial sulfonation of polystyrene (psp) was performed. an effective electrochemiluminescence (ecl) sensor based on psp with carbon nanotube (cnts) composite film was developed. cyclic voltammetry and electrochemical impendence spectroscopy were applied to characterize this composite film. the psp was used as an immobilization matrix to entrap the ecl reagent ru(bpy)(3)(2+) due to the electrostatic interactions between sulfonic acid groups and ru(bpy)(3)(2+) cations. the introduction of cnts into psp acted not only as a conducting pathway to accelerate the electron transfer but also as a proper matrix to immobilize ru(bpy)(3)(2+) on the electrode by hydrophobic interaction. furthermore, the results indicated the ecl intensity produced at this composite film was over 3-fold compared with that of the pure psp film due to the electrocatalytic activity of the cnts. such a sensor was verified by the sensitive determinations of 2-(dibutylamino)ethanol and tripropylamine.
