A novel single-armed Salamo-type bisoximes (H3L) has been designed and synthesized firstly. A new application of Salamo-type bisoximes in ion recognition is investigated in detail. H3L can act as a relay-sensor for ratiometric recognition of Zn2+/Cu2+ with high selectivity and sensitivity. The Zn2+ and Cu2+ complexes behave successive sensing of H+/OH- through fluorescence intensity increasing (ON) and decreasing (OFF). Meanwhile, the crystal structures of the Zn2+ and Cu2+ complexes based on H3L, [Zn(L)(mu-OAc)Zn] and Ku(L)(mu-OAc)Cu], have been determined by X-ray crystallographic analyses, respectively.
