7-Azaindole and its derivatives have been extensively investigated for uses in biological probes and imaging. In contrast, there have been very limited studies on the coordination chemistry and the applications of 7-azaindole and derivatives in materials science and in chemical bond activation. Our recent research has shown that 7-azaindolyl and derivatives are excellent blue emitters for organic light emitting diodes, they have rich coordination chemistry with both main group elements and transition metal ions, and their metal complexes display not only phosphorescence but also unusual and often unprecedented reactivity toward C-H and C-X bonds. This critical review discusses recent advances in these fields with focuses on new 7-azaindolyl derivatives and their metal complexes developed by our group. The luminescent properties and applications of 7-azaindolyl-based compounds will be presented. The reactivity of Pt(II) complexes toward C-H and C-X bonds, especially the steric impact of the bis(7-azaindolyl) chelate ligands and bimetallic cooperativity will be discussed (86 references).
7-氮茚及其衍生物在生物探针和成像方面的应用得到了广泛的研究。相比之下，在材料科学和化学键活化方面，7-氮茚及其衍生物的配位化学及其应用的研究非常有限。我们最近的研究表明，7-氮茚基及其衍生物是有机发光二极管的优良蓝色发射器，它们与主族元素和过渡金属离子具有丰富的配位化学，并且它们的金属配合物不仅显示磷光，而且对 C-H 和 C-X 键具有异常且通常前所未有的反应性。这篇评论性文章重点介绍了我们小组开发的新型 7-氮茚基衍生物及其金属配合物，讨论了这些领域的最新进展。将介绍基于 7-氮茚基化合物的发光性质和应用。将讨论 Pt(II)配合物对 C-H 和 C-X 键的反应性，特别是双（7-氮茚基）螯合配体的空间位阻和双金属协同作用的影响（86 篇参考文献）。
