Polarized Emission Property of the Lanthanide-complex Molecular Film

本研究的目的是利用薄膜方法开发镧系配合物的极化发射，这种方法利用了分子内有效的能量转移。本课题历时三年，制备了一种新型的天线分子，该分子由类似于邻菲罗啉的长烷基链组成，具有表面活性剂和金属络合配体的双重作用。试图在石英石板上形成铕配合物的LB膜。该薄膜表现出带偏振的发射现象。我们成功地找到了配体极化和与金属缔合之间的构象对获得极化发射的关键作用。对它们的完美操作的定量澄清正在进行中。

The aim of the present investigation is that the polarized emission of lanthanide complexes will be developed by using the thin film method, which used efficient intramolecular energy transfer in the molecules. During three years of this research project, a novel antenna molecule, which composed phenanthroline analogous with a long alkyl chain, was prepared, and had two role as a surfactant and ligand for the metal complexation. The LB film of a Eu complex with this ligand was tried to form on the quartz plate. This film showed ff-emission with polarization phenomena. We succeeded to find the key role of the conformation among the ligand polarization and association to the metal to obtain the polarized ff-emission. It is in progress to clarify quantitatively for their perfect manipulation.
