An unprecedented octahedral {Cd30} nanocage supported by twelve pendant-armed tetraacetate macrocyclic ligands

Abstract

An unprecedented octahedral {Cd(30)} nanocage supported by twelve pendant-armed tetraacetate macrocyclic ligands was synthesized through the reaction of macrocyclic tetraethyl ester and Cd(OAc)(2)·2H(2)O in a 1 : 2 stoichiometry, where the surface photovoltage and photoluminescent properties have been studied for the nanocage.

A tetragonal prismatic {Co32} nanocage based on thiacalixarene

“…To the best of our knowledge, this {Co 32 } coordination nanocage is not only a unique calixarene-based nanocage in a tetragonal arrangement but also has the highest nuclearity, even larger than the record {Cd 30 } cage. 12 Different from the octahedral {Co 24 } nanocages obtained with tripodal aromatic tricarboxylic acids, 10 CIAC-108 was designed with tetrazole ligands which were proved to be able to involve in the construction of the polynuclear metal-calixarene compounds. 13 Notedly, the tetrazole ligand was in situ generated by a click reaction.…”

Alkali-Metal-Templated Assembly of Two High-Nuclearity Cobalt Clusters Based on Thiacalix[4]arene

“…Owing to their potential applications in magnetism, optics, conductivity, catalysis and so forth, as well as the additional benefit of architectural beauty, high-nuclearity transition-metal (TM) coordination clusters have been receiving remarkable interest in chemistry and physics nowadays. Although reports on new polynuclear TM metal clusters with fascinating geometries and novel properties continue to appear, the synthesis of such giant clusters still remains a great challenge . Furthermore, the assembly of coordination complexes induced by different stimuli, such as anions, cations, pH value, temperature, solvent, light, and electric and magnetic fields, has been a hot topic, because such stimuli can have a large influence on the nuclearity and arrangement of metals in the resulting compounds, which may further lead to their structurally related physiochemical properties …”
