Energy transfer (ET) from ferrocene or ruthenium tris(bipyridine) functionalized light-harvesting units allows the first observation of sensitized near-infrared (NIR) lanthanide (Ln) luminescence (Lum.; see scheme, Exc.=excitation). Since the donating triplet state of the ruthenium tris(bipyridine) antenna is luminescent, the sensitization process could be studied in detail.
Klink et al. (Fri,) studied this question.
