制备了一系列取代的 1,8-二芳基萘 II-X，并测量了绕芳基萘键旋转的势垒。发现DELTA-G（双匕首）和sigma（para）值之间存在单调递增关系。这可以用两个芳基单元之间的空间极性相互作用来解释。
A series of substituted 1,8-diarylnaphthalenes, II-X, has been prepared, and the barrier to rotation about the aryl-naphthalene bond has been measured. A monotonic increasing relationship between DELTA-G(double dagger) and sigma(para) values has been found. This is interpreted in terms of a through-space polar interaction between the two aryl units.
