説明

<p>The development of typical element complexes, particularly those based on BODIPY and its derivatives, has recently become a key focus of research, primarily for applications in light-emitting devices, sensors, and photocatalysts. However, despite aluminum (Al) being in the same Group 13 as boron and its abundance and low cost, Al-based luminescent complexes have received surprisingly limited attention. This study introduces a novel class of functional dyes based on an aluminum-based dinuclear triple-stranded helicate, comprising three ligands and two aluminum ions. The complex, with its unique combination of rigidity and flexibility, enables intense luminescence and a large Stokes shift. Moreover, it exhibits circular dichroism (CD) and circularly polarized luminescence (CPL) properties arising from helical chirality. The creation of a mixed-ligand triple-stranded helicate also promotes efficient inter-ligand charge transfer (ILCT), facilitating the generation of excited triplet states. These distinctive properties highlighted its promising potential for diverse applications.</p>
