Example of ring slippage and its application to stimuli-responsive polymers. (IMAGE)
Caption
In ring-slippage, the number of atoms from a carbon ring involved in a particular bond changes. Multiple ring-slippage in 18-electron metallocenes is rare due to their stability, but as seen in this example, can be facilitated with pincer ligands.
Ring-slippage may be induced in several ways, including by applying mechanical force (e.g. pulling at either ends of metallocene-containing polymers). As molecular structure changes through ring-slippage, its properties will change too, which opens new possibilities for stimuli-responsive materials design.
