Von Wiley-VCH zur Verfügung gestellt
The ion pairs, consisting of the polarized porphyrin AuIII complex as a dipolar π-electronic cation, formed crystal-state ion-pairing assemblies based on antiparallel stacking structures stabilized by dispersion forces along with reduced electrostatic repulsion originating from the dipole–dipole interactions.
Abstract
A porphyrin AuIII complex comprising 5,10-penatafluorophenyl units was synthesized as a dipolar π-electronic cation. The π-electronic cation was combined with anions, including a bulky borate anion and planar π-electronic anions. The dipolar π-electronic cation formed crystal-state ion-pairing assemblies based on antiparallel stacking structures, which were stabilized by interionic dipole–dipole interactions.
