摘要：

Porphyrin-Au-III complexes were found to act as pi-electronic cations, which can combine with various counteranions, including pi-electronic anions. Single-crystal X-ray analyses revealed the formation of assemblies with contributions of charge-by-charge and charge-segregated assemblies, depending on the geometry and electronic state of the counteranions. Porphyrin-Au-III complexes possessing aliphatic alkyl chains formed dimension-controlled ion-pairing assemblies as thermotropic liquid crystals, whose ionic components were highly organized by pi-pi stacking and electrostatic interactions.
