Abstract

A new approach to design and synthesize efficient near-infrared luminescent ytterbium(III) compound has been achieved through incorporating a ring-opened rhodamine unit as energy donor with the excitation wavelength in the visible range (500 nm). The tetradentate binding unit of ligand fulfils the high coordination numbers of the lanthanide cation ensuring the efficient NIR emission.

摘要

通过将开环罗丹明单元作为能量供体与激发波长在可见光范围（500nm）相结合，实现了一种设计和合成高效近红外发光镱（III）化合物的新方法。配体的四齿配位单元满足了镧系阳离子的高配位数，确保了高效的近红外发射。
