Assembly of Near-Infrared Luminescent Lanthanide Host(Host-Guest) Complexes With a Metallacrown Sandwich Motif

Oscillators omitted: A self‐assembled inclusion complex between a LnIII[12‐metallacrown‐4]23+ sandwich motif (green and bronze) and a [24‐metallacrown‐8] (purple) is stable in methanol. The YbIII complex has a large quantum yield (0.89 %) and luminescent lifetime (14 μs) in methanol, which are attri...

Summary:Oscillators omitted: A self‐assembled inclusion complex between a LnIII[12‐metallacrown‐4]23+ sandwich motif (green and bronze) and a [24‐metallacrown‐8] (purple) is stable in methanol. The YbIII complex has a large quantum yield (0.89 %) and luminescent lifetime (14 μs) in methanol, which are attributed to the exclusion of high‐energy oscillators from within 6.7 Å of the emitting YbIII ion by the metallacrown topology.
