Long live the carrier! Hexa-peri-hexabenzocoronene derivatives, carrying paraffinic side chains terminated with ester–ether groups, form hexagonal columnar assemblies over a wide temperature range including room temperature. Within this temperature range, the lifetimes of charge carriers generated by laser flash photolysis are observed to be extremely long (14–40 ms).
