| Popis: | Liquid-crystalline (LC) Au complexes with siloxane groups at the termini of flexible chains were synthesized. The effects of the molecular and molecular aggregate structures on the luminescence behavior of the complexes were investigated. All complexes used in this study showed LC phases. No direct effect of the siloxane group on the luminescence behavior of the complexes in solution was observed. However, in condensed phases, different luminescence colors were observed depending on the aggregate structure due to the effect of intermolecular interactions. Thus, the luminescence color of the Au complexes can be controlled by the intermolecular interactions based on the structure of the molecular aggregates. The complex with the siloxane group developed in this study showed two different luminescence colors, which can be controlled by changing the aggregate structures induced by the phase transition.
