Optically pure dicyano oxa[7]helicenes and helicene-like molecules have been prepared and investigated for their optical behavior. The isomers of the intermediate 4,4'-biphen-anthrene-3,3'-diol were resolved by physically separating their 1-menthyl carbonate derivatives. In this work a mild method was developed to cleave ArOMe in presence of a cyano group. The optical rotation of atropisomeric diol, helicenes-like compounds and the oxa[7]helicenes was observed to be in increasing order, while the molecules also showed good response to circularly polarized luminescence.
已制备出光学纯的二氰基氧杂[7]螺旋烯及类螺旋烯分子，并对其光学行为进行了研究。中间体4,4'-联苯并菲-3,3'-二醇的异构体通过物理分离其碳酸1-薄荷酯衍生物得以拆分。在这项工作中，开发了一种温和的方法，可在氰基存在下裂解芳基甲醚。观察到阻转异构二醇、类螺旋烯化合物及氧杂[7]螺旋烯的旋光性呈递增顺序，同时这些分子对圆偏振发光也表现出良好的响应。
