Construction of a Ag₁₂ High-Nuclearity Metallamacrocyclic 3D Framework

Abstract

An unprecedented high-nuclearity metallamacrocycle-based 3D silver framework with formula {[Ag(2)(C(25)H(27)N(6)O)(2)](CH(3)OH)(H(2)O)(0.17)}(n) (1), built on the basis of dodecanuclear silver building blocks, has been synthesized and characterized, and it shows strong phosphorescence emission at 10 K, which is a consequence of the presence of intersystem crossing from singlet to triplet caused by the heavy-atom effect of silver ions.
