"Click" post-functionalization of a metal-organic framework for engineering active single-site heterogeneous Ru(iii) catalysts.

We present a general strategy for incorporating π-conjugated NNN-chelators (e.g., terpyridyl moiety) into a porous metal-organic framework (MOF) MIL-101(Cr) by using the "click" post-functionalization. The functionalized MOF could be used as a platform for metalation to yield highly active and stable single-site heterogeneous metal (e.g., Ru(iii)) catalysts.
