Abstract

A tetrametallic iridium-ytterbium complex has been synthesised that shows sensitized near-infrared emission (lambda(max) = 976 nm) upon excitation of the iridium unit in the visible region (400 nm) due to efficient energy transfer from the iridium units to the Yb(III) ion. The iridium phosphorescence is quenched nearly quantitatively while the ytterbium ion emits brightly in the NIR.

摘要

已合成一种四金属铱-镱配合物，当在可见光区域（400 nm）激发铱单元时，由于铱单元向Yb(III)离子的有效能量转移，该配合物呈现敏化近红外发射（λmax = 976 nm）。铱磷光几乎被定量猝灭，而镱离子在近红外区域明亮发光。
