WebThe “field strength” of a ligand describes how strong the coordination bond is, for a given metal and the ligand that is considered. The field strength is evaluated by considering how much it causes the d orbitals to split (DE), which can be related to the wavelength of light that is absorbed (See laboratory instructions). WebThe integration of strong coordination complexes and weak hydrogen bonds can optimize the mechanical properties of the elastomer, simultaneously providing high tensile strength (0.8 MPa), high stretchability (1326%), and moderate fracture toughness (7.1 MJ m −3).
