In this work, we show that a dithienylethene (DTE) modified dipicolinic amide ligand can be a versatile tool to modulate Eu(III) and Yb(III) luminescence using light as an external stimulus. The nature of the modulation depends on the lanthanide emitter: with the europium ion, the DTE ligand quenches the red luminescence upon ring closure, whereas with the ytterbium ion, ring closure can be used to turn on the luminescence in the NIR range.
在本研究中，我们表明，二噻吩乙烯（DTE）修饰的二吡啶甲酰胺配体可以作为一种通用工具，利用光作为外部刺激来调节铕（III）和镱（III）的发光。调节的性质取决于镧系元素发光体：对于铕离子，DTE配体在闭环时淬灭红色发光，而对于镱离子，闭环可用于开启近红外范围内的发光。
