We applied post-cyclization annulation to introduce a series of tethered S-shaped double [4]helicenes in which the intramolecular tether imposes a specific helical handedness. Introducing a tether and then shortening the tether length incrementally increase the pitch angle of [4]helicene, thus enabling a quantitative study of the effects of helicene's pitch on its electronic and (chiro)optical properties.
我们应用环化后环合反应引入了一系列相连的S形双[4]螺旋烯，其中分子内连接基团赋予了特定的螺旋手性。引入连接基团，然后逐步缩短连接基团的长度，会增加[4]螺旋烯的螺距角，从而能够定量研究螺旋烯螺距对其电子和（手性）光学性质的影响。
