General description

Tris(2,2′-bipyridine)ruthenium(II) hexafluorophosphate (Ru(bpy)3(PF6)2) is a conducting polymer that is majorly used as an active layer in electrochemical devices. It facilitates the formation of highly efficient and low voltage devices. It shows an external quantum efficiency of 0.35 and 400 cd/m2 at 3V.


Ru(bpy)3(PF6)2 may be used as a conjugating polymer in the development of light emitting electrochemical cell based devices such as light emitting diodes (LEDs). It is also used as a high-efficiency triplet emitter for OLED/Sensor research.

Nanofluidic electrochemical devices confine the volume of chemical reactions to femtoliters. When employed for light generation by electrochemiluminescence (ECL), nanofluidic confinement yields enhanced intensity and robust luminescence. Here, we investigate different ECL pathways, namely coreactant and annihilation ECL in a...

The excited-state properties of the transition metal complexes tris(2,2'-bipyridine) ruthenium(II) and tris(4,7-diphenyl-1,10-phenanthroline) ruthenium(II) are examined using picosecond time-resolved luminescence spectroscopy. For both complexes, direct observation of a short-lived high-energy emission with a lifetime of less than 4 ps is reported....
