Abstract

A Zn₃L₂-type metal organic aggregate featuring “six leaf windmill” shaped double cages constructed from a semi-rigid tripodal carboxyl acid ligand H₃TCPB (1,3,5-tri(4-carboxyphenoxy) benzene) exhibits sensitive luminescent response toward DMA with obvious intensity enhancement and red-shift. During the procedure, the host-gust interaction was supported by single-crystal-to-single-crystal transformation involving drastic conformational change of the molecular host upon μ₂-bridging H₂O release and the sensing mechanism was also discussed through theoretical calculations from charge separation hypothesis perspective. The DMA post-modified result of crystal transforming reveals high selective and effective naked eye reversible recognition for Co²⁺ ions through the dynamic and static quenching mechanisms. Moreover, the visual luminescent test paper was realized for potential application in concerns of the biology and environment.
