发光镧系元素配合物(Tb3+、Eu3+ 等)具有出色的生物学应用特性,包括极长的寿命和大的斯托克斯位移。然而,由于难以设计具有发光开/关开关的合适配合物,因此很少有关于基于镧系元素的功能探针的报道。在这里,我们合成了一系列由三个部分组成的复合物:镧系元素螯合物、天线和发光开关。天线是一个吸收光并将其能量传递给金属的芳环,开关是一个不同HOMO能级的苯衍生物。如果 HOMO 能级高于某个阈值,则复合物根本不发光,这表明镧系元素发光可以通过从开关到敏化剂的光诱导电子转移(PeT)进行调制。这种控制镧系元素发光的方法使功能性镧系元素配合物的合理设计成为可能,其中...

A study of structure-activityrelationships of a series of 'dipeptoid' CCK-B receptor antagonists was performed in which variations of the phenyl ring were examined while the [(2-adamantyloxy)carbonyl]-alpha-methyl-R)-tryptophan moiety of the potent antagonist CI-988 was kept constant. Since the main focus of this study was phenyl substituent variation, series design techniques were employed to insure
