[Ru(dpp)(3)][(4-Clph)(4)B](2) nanoislands directly assembled on an ITO electrode surface and its electrogenerated chemiluminescence.

摘要: In this work, solid-state tris(4,7-diphenyl-1,10-phenanthroline) ruthenium(II) ditetrakis(4-chlorophenyl)borate ([Ru(dpp)(3)][(4-Clph)(4)B](2)) nanoislands are assembled spontaneously and simultaneously on an indium-doped tin oxide (ITO) glass electrode surface via a facile dewetting procedure. The fabrication process is very simple also amenable to mass production. as-prepared ruthenium complex exhibit useful properties. more electrochemically active can produce strong, stable, reproducible electrochemiluminescence (ECL) signals using oxalate as the coreactant. self-assembled semiconductor-like broad, red-shift ECL spectrum. More importantly, they extend application of system from usual alkaline acidic conditions. pH turn-off behavior observed for first time serve ultrasensitive sensor around physiological 7.0. [Ru(dpp)(3)][(4-Clph)(4)B](2) signal efficiently inhibited by phenol even at low concentration (i.e., 20 nM), thus providing potential determination phenolic compounds in practical applications.
