结合吡嗪‐（pyzHA2−）和喹啉‐(quinoxaline‐（quinoHA2−）羟肟酸盐配体组装的两系列镧系(III)/锌（II）金属冠（MCs）的优点，我们在这里创建了水溶性混合配体MCs，其吸收范围扩展到可见光范围。ybiiii类似物在细胞培养基近红外（NIR）范围内表现出改善的光物理特性，促进了其在活HeLa细胞近红外光学成像中的应用。
By combining advantages of two series of lanthanide(III)/zinc(II) metallacrowns (MCs) assembled using pyrazine‐ (pyzHA2−) and quinoxaline‐ (quinoHA2−) hydroximate building blocks ligands, we created here water‐soluble mixed‐ligand MCs with extended absorption to the visible range. The YbIIIanalogue demonstrated improved photophysical properties in the near‐infrared (NIR) range in cell culture media, facilitating its application for NIR optical imaging in living HeLa cells.
