All kinds of fluorenophanes with bridging at 1,7-, 1,8-, and 2,7-positions of each fluorene unit have been successfully prepared. Dynamic structural properties clearly depend on the positions of the bridges. It has been found out that one (2,7)-bridged fluorene ring in the [2.2](1,8)(2,7)fluorenophane is bent to result in formation of the π-cavity.
我们成功地制备了在每个芴单元的 1,7-、1,8 和 2,7 位上桥接的各种芴。动态结构特性明显取决于桥的位置。研究发现,[2.2](1,8)(2,7)芴中的一个(2,7)桥接芴环弯曲后会形成π腔。
