2-hydroxybenzophenone-controlled self-assembly of enneanuclear lanthanide(III) hydroxo coordination clusters with an “hourglass”-like topology

Abstract

Enneanuclear lanthanide(III) hydroxo coordination clusters with an “hourglass”- or “sandglass”-like topology have been synthesized via 2-hydroxybenzophenone-controlled hydrolysis of the metal ions in ethanol

the EuIII 9 complex displays an intense red, metal-centered emission in the solid state at room temperature which is achieved by an indirect process (antenna effect). © 2017 Elsevier B.V.
