Abstract
Chiral oligopeptide-naphthalene/Eu(III) hybridized luminophores emit strong circularly polarised solution-state luminescence (CPL) from Eu(III) at 592 and 614 nm (|gCPL| ≤ 2.1 × 10−2). Although the peptide ligands have matching absolute configurations, the CPL sign is controllable by varying the number of naphthalene units and peptide/Eu(III) coordination ratio.
