Outline of Final Research Achievements

Disc-shaped π-conjugated molecules carrying immiscible side chain pairs such as hydrophobic/hydrophilic chains preferentially self-assemble into columnar structures to avoid the thermodynamically unfavorable contacts between immiscible chains. Moreover, the self-sorting binary columnar structures were realized when these compounds were mixed with usual disc-shaped molecules with hydrophobic chains. The demonstrated side chain molecular design strategy has potentially general for various π-conjugated cores.
