Abstract
Facile synthesis of xanthene-based Ï-stacked compounds consisting of face-to-face p-oligophenyls has been described. Just by mixing xanthene-4,5-diboronic acid and p-oligophenyls containing a benzenetetraol unit yielded cyclic compounds selectively due to the reversibility of the boronate esterification. In the ground state, weak Ï-Ï interactions between two p-oligophenyl moieties were observed, whereas their Ï-Ï interactions were clearly shown in the excited state.
