zirconacyclopentadienes (ZrPAHs). The efficiency of this process is demonstrated by a high‐yielding fivefold intramolecular coupling to form a helical ZrPAH with 16 fused rings (from a precursor with no fused rings). Several other PAH topologies are also reported. Protodemetalation of the ZrPAHs allowed full characterization (including by X‐ray crystallography) of PAHs containing one or more appended dienes with the

氧化锆环戊二烯(ZrPAHs)的PAH。高产率的五倍分子内偶联形成具有16个稠合环的螺旋ZrPAH(来自不带稠合环的前体)证明了该方法的效率。还报告了其他几种PAH拓扑。
