Chemomechanical reaction: The first octahedral ruthenium bipyridine complex that bears six polymerizable vinyl groups is used as an active cross-linker (see scheme, left). It is a key building block for cross-linked polymeric networks (right) thus allowing the construction of molecular architectures in chemomechanical soft materials.
