Let's do the twist! Helical chirality of cis‐azobenzene moieties, (P) or (M), was induced and unified by intramolecular axial chirality (see scheme). The twist direction depended on the axial chirality and the azobenzene link position of binaphthyls, but was independent of substituted groups. Moreover, these dyads were useful as chiroptical switches.
让我们开始吧!顺式-偶氮苯部分(P)或(M)的螺旋手性是由分子内轴向手性诱导并统一的(参见方案)。扭转方向取决于双萘基的轴向手性和偶氮苯连接位置,但与取代基无关。此外,这些二元组还可以用作按摩开关。
