设计了一种以[4]螺旋烯为面板的非圆柱形环芳烯，并通过R/ s -联芳键进行组装。通过对4对立体异构体（3对非对映体和1对对映体对）的分子结构测定，我们发现同系物的结构数学可以用双芳基的R/ s构型来描述，而不是用板取向来描述。与结构相关的环芳烯的比较加深了我们对环立体异构和结构化学的理解。
A noncylindrical cycloarylene was designed with [4]helicene as an arylene panel and was assembled by R/S-biaryl linkages. By determining the molecular structures of four stereoisomers (3 diastereomers and 1 enantiomer pair), we found that the structural mathematics of congeners can be best described by R/S-configurations of biaryls and not by panel orientations. Comparisons with structurally relevant cycloarylenes deepened our understanding of cyclostereoisomerism and structural chemistry.
