The synthesis and characterization of a new redox-active tetrathiafulvalene-terpyridine dyad are described. The complexation properties of this multifunctional dyad with various metal cations (Pb2+, Zn2+ and Fe2+) are further studied by UV–Visible spectrophotometry and cyclic voltammetry. This dyad displays colorimetric Pb2+, Zn2+, and Fe2+ detection and noticeable changes in the UV–Visible spectrum when complexed.
