Abstract

A heterometallic Tb-Pt complex, [Tb2Pt3(SAc)12(H2O)2] (SAc=thioacetate), was synthesized. Dual emission was modulated by the presence of a heterometallic Tb–Pt bonding environment. The heterometallic Tb–Pt bond lowers the symmetry of the Tb ion and enhanced the emission efficiency. In addition, the Tb–Pt complex shows field-induced multiple magnetic relaxation pathways. Furthermore, it served as an antenna for the observed dual emission. In other words, the heterometallic Tb–Pt bond has a significant effect on the luminescence and magnetic properties of the complex.
