Description
| Other Notes | Luminescent oxygen probe in optic sensors1,2; physical properties3 |
| Features and Benefits | Ruthenium-tris(4,7-diphenyl-1,10-phenanthroline) dichloride (Ru(dpp)) and Tris(4,7-diphenyl-1,10-phenanthroline)-ruthenium hexafluorophosphate (Ru(dpp)3(PF6)2) have been widely used as probes for luminescent detection and quantitation of oxygen. The fluorescence of both dyes (abs. λmax 455 nm, luminescence λ max 613 nm) is strongly reduced by molecular oxygen due to dynamic quenching. Therefore, it is a viable oxygen probe based on either measurement of intensity or decay time. The graph says that, e.g., at a partial pressure of 200 hPa the decay time (and intensity) of Ru(dpp)3(PF6)2 have dropped by a factor of 2 due to dynamic quenching. Tris(4,7-diphenyl-1,10-phenanthroline)ruthenium hexafluorophosphate proved to be superior for use in polystyrene membranes or beads. A protocol for embedding is given on our data sheet. |
