A chiral ligand-palladium complex was found to efficiently induce the inherent chirality of molecules during the macrocyclization process with ee values up to >99%. The resulting ABCD-type heteracalix[4]aromatics displayed excellent and pH triggered switchable electronic circular dichroism and circularly polarized luminescence properties.text::journal::journal article::research article
