Synthesis, Time-Resolved Luminescence, NMR Spectroscopy, Circular Dichroism and Circularly Polarised Luminescence Studies of Enantiopure Macrocyclic Lanthanide Tetraamide Complexes

Modulation of the frequency and polarisation of emitted light is achieved with the structurally rigid tetraamide complexes of lanthanides (Ln = Eu, Tb, Yb and Dy; Ar = Ph, p‐X‐Ph; X = Br, CN, CO2Me; see picture). The configuration at C determines the metal‐centred helicity, and overall quantum yield...

Summary:Modulation of the frequency and polarisation of emitted light is achieved with the structurally rigid tetraamide complexes of lanthanides (Ln = Eu, Tb, Yb and Dy; Ar = Ph, p‐X‐Ph; X = Br, CN, CO2Me; see picture). The configuration at C determines the metal‐centred helicity, and overall quantum yields of up to 0.81 were measured in D2O.
