Outline of Final Research Achievements

Herein, we adopt for the first time, a kinetic approach to control the length and number of helical twist of aggregates of europi-um(III) complexes showing high circular polarized luminescence (CPL). The molecular systems used for self-assembly are four pairs of enantiomers of europium complexes bearing heptafluorobutyryl camphorate (hfbc) ligands that forms large helical structures under suitable experimental conditions. The europi-um(III) complex Cs+[Eu((+)-hfbc)4] shows the highest available CP at pre-sent,but its intrinsic emission quantum yield has left room for improvement. A comparative study between the aggregates and the monomeric complexes revealed the enhanced luminescence and CPL were displayed in the aggregated state. We also observed enhanced CPL in the aggregated structures of helical PBI dimers, which form molecular wires and nanoparticles depending on aggregation conditions. FInally, we observed CPL activity of chiral Silver nanoclusters for the first time.
