Noncovalent interactions in inorganic supramolecular chemistry based in heavy metals. Quantum chemistry point of view

Abstract

Complexity is a concept that is being considered in chemistry as it has shown potential to revealinteresting phenomena. Thus, it is possible to study chemical phenomena in a new approachcalled systems chemistry. The systems chemistry has an organization and function, which areregulated by the interactions among its components. At the simplest level, noncovalent interac-tions between molecules can lead to the emergence of large structures. Consequently, it is pos-sible to go from the molecular to the supramolecular systems chemistry, which aims to developchemical systems highly complex through intra- and intermolecular forces. Proper use of theinteractions previously mentioned allow a glimpse of supramolecular system chemistry in manytasks such as structural properties reflecting certain behaviors in the chemistry of materials, forexample, electrical and optical, processes of molecular recognition and among others. In the lasttime, within this area, inorganic supramolecular systems chemistry has been developed. Thosesystems have a structural orientation which is defined by certain forces that predominate in theassociations among molecules. It is possible to recognize these forces as hydrogen bonding,π-πstacking, halogen bonding, electrostatic, hydrophobic, charge transfer, metal coordination, andmetallophilic interactions. The presence of these forces in supramolecular system yields certainproperties such as light absorption and luminescence. The quantum theoretical modeling playsan important role in the designing of the supramolecular system. The goal is to apply supramo-lecular principles in order to understand the associated forces in many inorganic molecules thatinclude heavy metals for instance gold, platinum, and mercury. Relevant systems will be studiedin detail, considering functional aspects such as enhanced coordination of functionalized molec-ular self-assembly, electronic and optoelectronic properties.
