INOR 579 |
| Salts of iridium and ruthenium complexes with cyclometallating and polypyridyl ligands have been studied for use as oxygen sensors. Crystalline solids of these lumiphores have void space due to the large bulky counterions utilized in crystallization. The void space in the crystals provides a means for oxygen to diffuse to the luminescent site where quenching of the emission occurs through energy transfer to the oxygen. The use of porous crystalline materials can eliminate the complications (multiple sites, decomposition) that host materials such as polymer matrices or zeolites, cause in the quenching process. Synthetic details as well as studies of the oxygen sensing of these complexes will be presented. |
