Circumtrindene (6, C36H12), one of the largest open geodesic polyarenes ever reported, exhibits fullerene-like reactivity at its interior carbon atoms, whereas its edge carbons react like those of planar polycyclic aromatic hydrocarbons (PAHs). The Bingel-Hirsch and Prato reactions - two traditional methods for fullerene functionalization - afford derivatives of circumtrindene with one of the interior
Circumtrindene (6, C36H12) 是有史以来最大的开放测地聚芳烃之一,其内部碳原子表现出类似富勒烯的反应性,而其边缘碳的反应类似于平面多环芳烃 (PAH)。Bingel-Hirsch 和 Prato 反应 - 两种传统的富勒烯官能化方法 - 提供环三茚的衍生物,其中一个内部 6:6 C=C 键被修饰。另一方面,环三茚边缘的官能化可以通过普通的亲电芳香取代来实现,这是平面多环芳烃最常见的反应。这种外围功能化已被用于通过随后的偶联反应扩展聚芳烃的 pi 系统,并用于探测烃碗周围凹/凸空间的磁环境。对于两类功能化,
