The reactivity of the triflate functionalized iridapentalene 1, [Ir{CHC(CH₂C(CO₂Me)₂CH₂)CCCHC(OTf)CH}(CO)(PPh₃)₂]OTf, with C-, N-, O- and S-centered neutral nucleophiles was studied, leading to the isolation of a wide array of irida–carbolong derivatives. As an extension, a polycyclic complex with a rare six-fused-ring structure was constructed. This strategy provides a new route for the construction of functionalized metallaaromatic complexes, and the resulting iridacycles exhibit broad spectral absorption ranges, making them potential photoelectric materials.

Carbolong 化学：三氟甲磺酸酯官能化的 iridapentalene 的亲核芳香取代

三氟甲磺酸酯官能化的 iridapentalene 1, [Ir{ CHC(CH ₂ C(CO ₂ Me) ₂ CH ₂ ) CC CHC(OTf) CH}(CO)(PPh ₃ ) ₂ ]OTf 与C -、N - 的反应性, O - 和S对中心中性亲核试剂进行了研究，从而分离了多种 irida-carbolong 衍生物。作为扩展，构建了具有稀有六稠环结构的多环复合物。该策略为功能化金属芳香族配合物的构建提供了一条新途径，由此产生的虹彩环具有广泛的光谱吸收范围，使其成为潜在的光电材料。
