Abstract

Abstract : Two-dimensional confinement enables thermodynamic control over the competition between macrocycle and chain formation. Abstract : Control over the competition between an organometallic hexamer macrocycle and oligomer chains formed from the non-alternant aromatic 1, 3-dibromoazulene (DBAz) precursor has been achieved in surface-assisted synthesis on a copper(111) surface. In contrast to kinetic reaction control via the high-dilution principle, the ring formation is achieved here by thermodynamic control, which is based on two-dimensional (2D) confinement and reversible bonds.
