substituted 2,2’-bipyridine ligand) complexes based on polypyridine-functionalized Dawson polyoxometalate (1-3) has been synthesized. The new hybrids (4-6) were characterized by various analytical techniques, including absorption, vibrational and luminescence spectroscopies as well as electrochemistry. Both units, the polyoxometalate and the transition metal complex, retain their intrinsic properties
合成了一系列基于聚吡啶官能化的道森多金属氧酸盐(1-3)的[Re(CO)3Br(N ^ N)](N ^ N =取代的2,2'-联吡啶配体)配合物。新型杂种(4-6)的特征在于采用了多种分析技术,包括吸收光谱,振动光谱和发光光谱以及电化学。多金属氧酸盐和过渡金属络合物这两个单元均保持其固有特性。它们在新制备的杂种中的组合导致在高能可见光区的光敏性提高。但是,由于形成了电荷分离态Re(II)– POM-,观察到[Re(CO)3Br(N ^ N)]配合物的发射完全淬灭,如淬灭实验以及通过DFT进行理论建模。
