Flattening helices while keeping the handedness: On-surface cyclodehydrogenation of bishelicene enantiomers leads stereospecifically to (M,M) and (P,P) chiral planar polyaromatic hydrocarbons. This is followed by their homochiral aggregation into a 2D conglomerate. Thermally induced cyclodehydrogenation proceeds stereospecifically to chiral, planar coronocoronene. Such a reaction is a special example of topochemistry in which enantiospecific conversion is supported by the alignment of the reactant by the surface.

Bishelicenes 的立体有择表面环脱氢反应：从螺旋到平面手性的旋向性保存

在保持旋向性的同时压平螺旋：双螺旋烯对映体的表面环化脱氢立体定向地导致（M，M）和（P，P）手性平面聚芳烃。随后是它们的同手性聚集成二维聚合体。热诱导的环脱氢反应立体定向地进行手性、平面冠状晕苯。这种反应是拓扑化学的一个特殊例子，其中对映特异性转化由反应物通过表面的排列来支持。
