BINOL and triazole-containing Janus rings and 29-8-29-membered tricyclic ladder-type hybridized siloxane: application in the fluorescence sensing of anions

Abstract

A new BINOL and triazole containing 29-8-29-membered tricyclic ladder type siloxane was prepared.

Recent progress in ladder-like polysilsesquioxane: synthesis and applications

“…137 Additionally, they reported the synthesis of tricyclic ladder siloxane through intramolecular cyclization of Janus rings in the presence of B(C 6 F 5 ) 3 . [138][139][140][141][142][143] This method has broadened the scope of ladder siloxanes by incorporating more siloxane units into the ring compared to traditional 6-8-6 or 8-8-8 membered-ring systems. Although this differs from polysilsesquioxanes, the focus of our review, it provides insight into researchers' approaches on ladder-type siloxanes.…”
