Fig. 1: Our synthetic concept of bowls based on p-HBC.
From: Trichalcogenasupersumanenes and its concave-convex supramolecular assembly with fullerenes
Each of bay regions of p-HBC are bridged by one divalent group (X or Y), supersumanene are defined as X = Y = C, while heterosupersumanene are defined as X,Y = heteroatom.
