Programmable self-assembly of water-soluble organo-heterometallic cages [M 12 M' 4 L 12 ] using 3-(3,5-dimethyl-1H-pyrazol-4-yl)pentane-2,4-dione (H 2 L)

Programmable self-assembly of water-soluble organo-heterometallic cages [M 12 M' 4 L 12 ] using 3-(3,5-dimethyl-1H-pyrazol-4-yl)pentane-2,4-dione (H 2 L)

A bifunctional ligand H L featuring primary (pyrazole) and secondary (acetylacetone) coordination sites was preferentially reacted with dimetallic [M (NO ) ](NO ) linkers at the pyrazolyl end of H L, giving rise to dimetallic corners. Subsequently, the corners serve as the secondary site with M'...

Zusammenfassung:A bifunctional ligand H L featuring primary (pyrazole) and secondary (acetylacetone) coordination sites was preferentially reacted with dimetallic [M (NO ) ](NO ) linkers at the pyrazolyl end of H L, giving rise to dimetallic corners. Subsequently, the corners serve as the secondary site with M' to form water-soluble organo-heterometallic [M M' L ] cages in a stepwise mode.
