摘要：

The electroanalysis of small quantities (picomoles) of water-insoluble compounds at the air/water interface of a Langmuir minitrough by transfer to an electrode and on trough voltammetry is described. Experiments were carried out with an amphiphilic surfactant, Ru(bpy)2(bpy-C19)2+ (where bpy = 2,2'-bipyridine and C19 = CH2NHOC(CH2)16CH3), as well as tris(4,4'-diphenyl-2,2'-bipyridyl)ruthenium(II), the tris(4,7-diphenyl-1,10-phenanthroline) complexes of Ru(II) and Fe(II), and several aromatic phenols and amines. The effects of several parameters, such as electrode surface hydrophobicity and transfer conditions, are considered and ontrough electrogenerated chemiluminescence (ECL) is shown to be useful in imaging the distribution of analyte on the electrode surface.
