DOTA-tetraamide ligands having extended phenol or pyridine substituents have been synthesized. The (5)D(0) --> (7)F(J) deltaJ = 1 and 2 emission bands in the corresponding europium(III) complexes differ in their sensitivity to solution pH. This offers the potential for developing pH responsive probes for in vivo imaging that are independent of probe concentration.
已经合成了具有扩展的苯酚或吡啶取代基的DOTA-四酰胺配体。(5)D(0)->(7)F(J)deltaJ = 1和相应euro(III)配合物中的2个发射带对溶液pH的敏感性不同。这为开发用于体内成像的pH响应探针提供了潜力,该探针与探针浓度无关。
