Outline of Final Research Achievements

Artificial large and sophisticated molecular systems, such as artificial enzyme, artificial molecular scaffold, and artificial molecular architecture are of current interest. We have developed peptide/protein-inspired building blocks such as 1,4-bis(ethynylthienyl)arenes and 4,7-dibromobenzo[b]thiophene, for construction of linked molecular systems containing main axis and various side chains. In this research, a modified synthetic route to 4,7-dibromobenzo[b]thiophene, using 1-adamantanethiol, was developed and the dibromobenzothiophene was utilized for syntheses of oligoarenes, whose structures were inspired by folding of proteins.
