| Inorganic complexes show great promise as molecular probes and luminescence-based sensors. The majority of work uses Ru(II), Re(I), and Os(II) complexes with α-diimine ligands (e.g., 2,2’-bipyridine, 1,10-phenanthroline, and analogues). The rational design of practical systems requires an intimate understanding of the interactions between the probe or sensor molecule and the polymer-based support or the target. Advances in understanding the interactions of metal complexes and polymeric supports will be discussed using examples from oxygen and pH sensors. Conventional, two photon, and confocal fluorescence microscopy will be shown to be a powerful tool in sorting out the system complexities. In addition, photochemical results demonstrate the unique role the polymer can play in the photostability of the sensor molecules. |
