Monoaryne and monoisobenzofuran analogues of a C(3v)-symmetrical tribenzotriquinacene (TBTQ) were generated in situ and trapped with various dienes and dienophiles, respectively. In this way, a series of single-wing extended TBTQ derivatives bearing the bowl-shaped TBTQ unit in different topographical expositions have become accessible. This includes some novel tribenzotriquinacene "dimers", in which two TBTQ bowls are attached in syn- or anti-orientation at the terminal positions of rigid linker units. Several of these compounds have been characterized by both spectroscopy and X-ray structural analysis. The efficient access to the TBTQ "dimers" may lay a useful foundation for further studies of novel container compounds and supramolecular architectures.
Monoaryne 和 monoisobenzofuran 类似物是一种 C(3v)-对称的三苯并三嗪（TBTQ），它们分别与各种二烯和双烯发生反应并被捕获。通过这种方式，一系列具有不同拓扑暴露的单翼扩展 TBTQ 衍生物成为可能。其中包括一些新型的三苯并三嗪“二聚体”，其中两个 TBTQ 碗在刚性连接单元的末端位置以顺式或反式取向连接。这些化合物中的几个已通过光谱和 X 射线结构分析进行了表征。高效获得 TBTQ“二聚体”可能为进一步研究新型容器化合物和超分子结构奠定有用的基础。
