Novel poly (zinc phthalocyanine) (poly(ZnPc)) nanoribbons have been obtained by polycyclotetramerization of bifunctional ZnPc monomers. The microstructures of poly(ZnPc) nanoribbons are characterized by scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, X‐ray diffraction, and thermalgravimetry. Due to its unique two‐dimensional structure and rich functionality, the poly(ZnPc) nanoribbons exhibit excellent sensitivity in detecting lead ions (Pb 2+ ) by using anodic stripping voltammetry (ASV) method, and the detection limit for Pb 2+ is 10 −10 mol L −1 in aqueous media, which is much attractive for the development of portable and highly sensitive heavy metal ion sensors.
