No.2-21 アスファルテンのモデル分子合成の試み

抄録

This paper summarizes molecular models of asphaltene and synthetic model compounds in past studies. Asphaltenes were considered to contain continental-type and/or archipelago-type molecules. The former consists of one large polycyclic aromatic unit with side chains, and the latter have several small polycyclic aromatic units that are connected to each other. In the last decade, researchers have tried to synthesize model compounds of asphaltene. For example, hexabenzocoronene with straight side chains as a model of continental-type molecules, and a nickel porphyrin-derived compound, pyrenederived compounds, and steroid-derived naphthoquinoline compounds as models of archipelago-type molecules. However, the model compounds neither have the same chemical structures as the proposed molecular models, nor show similar aggregation behavior as asphaltene.
