Ligands based on 2,2'-bipyridine and valinamide moieties induce circularly polarized luminescence in their europium complexes. Both the R and S enantiomers of the complexes were successfully obtained. Single-crystal X-ray analysis of the racemic crys

An acyl group derived-bipyridine ligand and Eu form 3:2 complexes. The structure and luminescence behaviour were evaluated, and we found an unexpected bi-nuclear complex system, which induces effic...

Linearly polarized luminescence (LPL) in films of europium ions was induced by using naphthoic acid adopted alkyl chain (NaphC15), which plays the roles of both surfactant and photo-antenna. The synthesis of NaphC15 was newly developed, and the Eu co

We structurally and spectroscopically investigated a series of praseodymium (Pr) complexes with eight ligands that form helicate molecular structures. The mother ligand skeleton (L) has two bipyridine moieties bridged with ethylenediamine. The bridge

The optical properties of polycyclic aromatic hydrocarbon fluorophores, such as pyrene and perylene, are controlled by confined spaces of meso- and supermicropores in a silica matrix. The quantum yield of fluorescence from monodispersed pyrene and pe
