Triangular Cd(II)-Sm(III) Schiff Base Complex with Dual Visible and Near-Infrared Luminescent Responses to Nitro Explosives
Two d-4f complexes [Zn2NdL2 (OAc)(2)]center dot OH (1) and [Cd3Sm3L3(OAc)(6) (OH)(3)] (2) with a designed Schiff base ligand NN'-bis(3-methoxysalicylidene)(binaphthyl)-1,4-diamine (H2L) were synthesized. The Schiff base ligands coordinate with metal ions by mu(2) (eta(1):eta(2):eta(1):eta(1):eta(2):eta(1)) and mu(2) (eta(1):eta(2):eta(1):eta(1):eta(2):eta(1)) modes in the complexes, which show typical lanthanide emissions. The triangular Cd-Sm complex 2 shows both visible and NIR luminescent responses to nitrobenzene explosive 2,4,6-trinitrophenol (PA).
