Synthesis of Nitrogen containing heteroaromatic system for building up supramolecular architecture

Abstract

Weak interactions are hierarchy for formation of supramolecular self-assembly in chemical engineering. A noncovalent interaction is a type of chemical bond that does not involve sharing of pairs of electrons. Non-covalent interactions play a vital role in chemistry, biology and material sciences. In Chemistry, biology, materials science and crystallography aromatic interaction exhibit the essential class of intermolecular forces, weak bonds formed between different molecules or within different parts of a large molecule are not strong enough to hold molecules together even then they are extremely important because of their presence in large number in a molecule. Self-assembly of aromatic compound favour via and#960; and#960; (face-to-face) interactions either C-H...and#960; interactions (T-shape geometry, edge-to-face or herringbone interactions) or with both. Hydrogen-bonding and and#960; and#960; interaction are of at most importance among non-covalent interactions in supramolecular chemistry. newlineWeak noncovalent interactions like stacking interactions (arene-arene/arene/and#960;···and#960; interactions), lone pair-and#960; interactions etc., are not well understood. Due to their weak nature they are difficult to observe in presence of stronger forces such as classical hydrogen bonding and thus they are difficult to study both theoretically and experimentally. These forces often work together and their collective effect brings a change in molecular structure as well as in supramolecular structure. newline
