Scaffolding a Cage-Like 3D Framework by Coordination and Constitutional Dynamic Chemistry
摘要:
By exploiting the supramolecular assistance of a sterically encumbered phenanthroline-Cu+ motif, we report on the self-assembly of a trigonal nanoprism, its post-self-assembly functionalization, and transformation into a cage-like 3D framework with distinct compartments.
Triazatriangulenium ions have previously been used as platforms :to prepare self-assembled monolayers of functional molecules, such a azobenzenes with vertical orientation and that are free-standing on gold surfaces: We have now prepared azobenzenes that are spanned between two posts which are attached on two platforms. Absorbed on a gold surface, the azobenzene should be laterally oriented at a distance of mare than 4 angstrom above and thus electronically decoupled from the surface, and the system should perform a muscle-type movement upon isomerization.
