synthesis and characterization of the so far largest polycyclic aromatic hydrocarbon (PAH), containing 222 carbon atoms or 37 separate benzene units. First a suitable three-dimensional oligophenylene precursor molecule is built up by a sequence of Diels-Alder and cyclotrimerization reactions and then planarized in the final step by oxidative cyclodehydrogenation to the corresponding hexagonal PAH.

在本文中,我们介绍了迄今为止最大的多环芳烃(PAH)的合成和表征,它包含222个碳原子或37个单独的苯单元。首先,通过一系列的Diels-Alder反应和环三聚反应,构建合适的三维低聚亚苯基前体分子,然后在最后一步通过氧化环脱氢将其平面化成相应的六边形PAH。结构验证基于同位素分辨的MALDI-TOF质谱,并通过UV / Vis光谱研究了电子特性。
