Two Octa-Nuclear {Ln₈} (Ln = Tb, Dy) Complexes with “4 + 4” Covalent Organic Macrocycles: Structure, Solution Behavior, Luminescence, and Magnetic Properties

Abstract

In this study, two octa-nuclear lanthanide complexes consisting of a templated Ln 8 (Ln = Tb, Dy) cluster and a ″4 + 4″ type Schiff-base covalent organic macrocycle, named Ln 8 L 4+4 , were constructed successfully. The stepwise solution assembly process of Tb 8 L 4+4 from the initial organic subcomponents and metal templates was tracked as Tb
