The Effects of Nonionic Surfactants on the Tris(2,2'-Bipyridl) Ruthenium(Ii)-Tripropylamine Electrochemiluminescence System
When oxidized in the presence of tri-n-propylamine (TPA), the molecule Ru(bpy)₃²⁺ (bpy= 2,2'-bipyridyl) undergoes reactions to produce electrochemiluminescence (ECL). In this investigation, the effects of the nonionic surfactants Nonidet P40®, Thesit®, and Triton X-100® were studied. ECL occurs in …

Evaluation of solid-state light-emitting devices based on the tris-chelated ruthenium (II) complexes
Organic light-emitting devices have the potential to create a new range of applications. They are versatile because their physical properties (color, emission efficiency) can be fine-tuned by the manipulation of their chemical structures. In this work, the novel technology of Ru(bpy)t-based devices …
