Abstract Self-assembly of water soluble highly fluorescent perylene tetracarboxylic (PTCA, Φf = 0.67) dye via metal coordination has been leads to the selective fluorescence sensing of Cu2+ and Pb2+ ions at neutral pH and Ag+ ions sensing via nanoparticles formation at basic medium. High-resolution transmission electron microscopic (HR-TEM) analysis revealed the conversion 1-D nanostructures of PTCA to spherical aggregates with Cu2+ and hexagonal prisms with Pb2+ ions. However, Ag+ ions were… Expand
