Coronates, Spherical Containers, Bowl-Shaped Surfaces, Porous 1D-, 2D-, 3D-Metallo-Coordination Polymers, and Metallodendrimers

Abstract

Supramolecular coordination cages and polymers bear exceptional advantages over their organic counterparts. They are available in one-pot reactions and in high yields and display physical properties that are generally inaccessible with organic species. Moreover, their weak, reversible, noncovalent bonding interactions facilitate error checking and self-correction. This review emphasizes the achievements in supramolecular coordination container as well as polymer chemistry initiated by serendipity and their materialization based on rational design. The recognition of similarities in the synthesis of different supramolecular assemblies allows prediction of potential structures in related cases. The combination of detailed symmetry considerations with the basic rules of coordination chemistry has only recently allowed for the design of rational strategies for the construction of a variety of nanosized spherical containers, bowls, 1D-, 2D-, and 3D-coordination polymers with specified size and shape.

Exploring ‘new’ bioactivities of polymers at the nano–bio interface

“…Moreover, in forming higher-order structures, polymers with 'active' chemical groups, such as amidogen, may gain new biological activities. These 'active' functional groups can drive the polymer to form more complex 3D nanostructures that may endow the polymer with unforeseen biological activities [36]. In response to such pressing demand for comprehensive information about the structure-function relationship of polymers, technologies and methods to study protein biochemistry, in tandem with platforms for high-throughput screening and establishment of polymer libraries, may be utilised to accelerate the identification and development of polymers as drug candidates.…”

Gold-Based Coronands as Hosts for M3+ Metal Ions: Ring Size Matters

“…Similar mechanisms apply for metal-based compounds, where mainly coordinative bonds are responsible for the self-assembled formation of supramolecular aggregates. Such systems are of widespread interest in different fields of research, e.g., as molecular nanocontainers, molecular magnets, catalysts and as models (or even mimics) of reactive centers in bioinorganic systems [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ].…”

Eu(III) Tetrahedron Cage as a Luminescent Chemosensor for Rapidly Reversible and Turn-On Detection of Volatile Amine/NH3

“…As the simplest three-dimensional (3D) architectures, tetrahedra are the most reported metal−organic polyhedra, and their constructions have been well documented by Saalfrank, 36,37 Raymond, 38−41 Ward,42,43 Nitschke, 44−47 and others. 48−53 However, only few successful examples with Ln(III) ions as vertexes are reported in light of their variable coordination numbers (6−12) and multivariate coordination spheres.…”
