A series of cationic and neutral p-bromo and p-nitropyridine substituted Eu(III) and Gd(III) coordination complexes serve as versatile synthetic intermediates. This approach allows the late stage tuning of absorption and emission spectroscopic properties for Eu(III) complexes, and provides easy access to the corresponding Eu(II) analogues, aiding the development of Gd(III) EPR spin probes that can
一系列阳离子和中性对溴和对硝基吡啶取代的 Eu(III) 和 Gd(III) 配位络合物可作为多功能合成中间体。这种方法可以对 Eu(III) 配合物的吸收和发射光谱特性进行后期调整,并可以轻松获得相应的 Eu(II) 类似物,从而有助于开发可轻松与 EPR 偶联的 Gd(III) EPR 自旋探针。生物分子,在温和的条件下。
