摘要： A simple method for immobilization of tri(4,7-diphenyl-1,10-phenanthroline) ruthenium(II) ditetrakis(4-chlorophen-yl) borate ([Ru(dpp)_3][(4-Clph)_4B]_2) on carbon fiber electrodes was developed. Excellent electrochemical activity and electrochemiluminescence (ECL) signal of the coated carbon fiber electrodes were observed using oxalate as the co-reactant. In addition, the effects of pH, scan rate, nitrogen and oxygen on ECL intensity were also studied. To demonstrate the reliability, the coated carbon fiber electrodes were used as ECL detectors and very low concentration of phenol was detectable (5.0 x 10~~8 M).
