This report describes the synthesis of a carbon nanotube-bound dendrimer and three carbon nanotube-bound monometallic complexes and their use as catalysts. The polyamidoamine third generation dendrimer used here incorporates pyrazole-triazole moieties suitable for ligating iridium(III) centres. The monometallic complexes use the same pyrazole-triazole ligands coordinated to an iridium(III) centre. All catalysts were characterized using ICP-AES and XPS to evaluate their metal loadings on the carbon surface with significantly higher relative weight percentage of iridium determined for the denrimeric species. The catalytic activity and practicality of the formed catalysts were tested using two different intramolecular hydroamination reactions.

与碳纳米管结合的树枝状聚合物和相应的单金属铱 (III) 催化剂用于加氢胺化转化

本报告描述了碳纳米管结合的树枝状聚合物和三个碳纳米管结合的单金属配合物的合成及其作为催化剂的用途。此处使用的聚酰胺胺第三代树枝状聚合物包含适用于连接铱 (III) 中心的吡唑-三唑部分。单金属配合物使用与铱（III）中心配位的相同吡唑-三唑配体。使用 ICP-AES 和 XPS 对所有催化剂进行表征，以评估它们在碳表面上的金属负载量，并为树枝状物质确定了显着更高的铱相对重量百分比。使用两种不同的分子内加氢胺化反应测试了所形成催化剂的催化活性和实用性。
