圈烯（circulene）即尾部相稠合的邻并苯，是“拱形芳烃”（geodesic polyarene）的一类。[5]圈烯（碗烯）、[6]圈烯（蒄）、[7]圈烯 与[12]圈烯（凯库勒烯）都已合成。[5]圈烯为碗形，[6]圈烯为平面结构，[7]圈烯则具类似马鞍的特殊结构（类比杯芳烃）。

A circulene is a macrocyclic arene in which a central n-sided polygon is completely surrounded and fused by benzenoids. [5]circulene (corannulene), [6]circulene (coronene), [7]circulene, and [12]circulene (kekulene) have all been synthesized in the laboratory. These compounds belong to a larger class of geodesic polyarenes. Whereas [5]circulene is bowl-shaped and [6]circulene is planar, [7]circulene has a unique saddle-shaped structure (compare to cones and partial cones in calixarenes). Conceptually related compounds are the helicenes.
