キラルネマチック相における金錯体の発光挙動

The luminescence efficiency of gold complexes are enhanced by aggregation of molecules due to the intermolecular aurophilic interaction. Since this intermolecular interaction occurs depending on the distance between two gold atoms, we need to control the aggregated structures of molecules in materials. Previously, we have synthesized liquid-crystalline gold complexes with a chiral center in the flexible chain to control the aggregated structure. Those complexes showed the strong luminescence, as the helical pitch gets shorter, by changing the mol fraction of chiral dopant in the ternary mixture of fold complex, chiral dopant, and 5CB. In this study, we synthesized the gold complex with terpenoid structure as a flexible chain including chiral moiety (Figure 1), and examined the properties. Furthermore, we mixed with 5CB to induce chiral nematic liquid-crystalline (Nem* LC) phase and examined the photoluminescence behavior in this Nem* LC phase.
