"Click" methodology for synthesis of functionalized [3]catenanes: toward higher interlocked structures.

"Double Click" and it's locked: Copper(I)-templated synthesis in conjunction with "click" chemistry has been applied in a straightforward manner for the preparation of functionalized [3]catenanes. This methodology allows the construction of higher interlocked architectures, including polymers and networks as well as electron donor-acceptor nanomaterials suitable for investigation of long-range photoinduced electron-transfer processes.
