Abstract

This article describes the synthesis of a selective dual emissive intramolecular charge transfer (ICT) receptor for zinc ion in acetonitrile, exhibiting aggregation induced emission enhancement (AIEE) in the solid state due to the formation of inter- or intra-molecular hydrogen bonds and aromatic donor–acceptor interaction with H- or J-aggregation.
