New functionalized derivatives of bimesitylene as precursor for obtaining of polyfunctional ligands

Abstract

An important class of organic compounds, which are found in many natural products, such as biologically active compounds, alkaloids or natural dyes, is represented by biaryls and their derivatives. One of the interesting representatives of this family is bimesitylene due to the fact that, for steric reasons, the two conjugated aromatic rings are perpendicular to each other. In this molecule, the four aromatic hydrogen atoms are arranged at the corners of a tetrahedron, and their replacement by chelating functional groups could lead to derivatives capable of forming three-dimensional (3D) networks with metal ions. Thus, the synthesis of ligands based on functionalized derivatives of bimesitylene is promising for the subsequent assembly of metal-organic frameworks, as promising materials in sorption processes.
