Cu(II) metal ions are a significant pollutant that causes toxicity in the world water systems. Therefore, water-soluble chemosensors for Cu(II) ion detection are very important for Water Management and Conservation Solutions in the environment. Chemosensors are vital in environmental monitoring as they help to detect pollutants like heavy metals and toxins. Notably, Cu(II) ions are an essential metal for the human body and environment; therefore, their detection is crucial. Recently, a novel water-soluble naphthalene diimide was published as a highly selective FLUORESCENT-ON Chemosensor for Cu(II) ions. The Chemosensor detection limit is 1.11 μM, lower than the WHO (World Health Organization) standard. Notably, the water-soluble naphthalene diimide is a novel candidate for a Fluorescence-On Chemosensor for Cu(II) ions. The project's objective is to prepare a novel preliminary prototype of a Fluorescence-On Chemosensor for Cu(II) ions at the end of the Research Project. The work methodology will consist of three steps:
1-First, the HUNEC2025 Team will synthesise the chemosensor according to the literature data.
2- Afterwards, the Natural Bond Orbital (NBO) analysis will be studied for modelling to understand better the mechanisms underlying metal complexation of the water-soluble chemosensors with Cu(II) ion and get detailed insights into the electronic structure and bonding characteristics (using Gaussian 09 program). Notably, the NBO analysis will provide a detailed structure of electronic interactions, charge distribution, and bonding dynamics to support the optimization of the complexation of Cu(II) ions with a chemosensor.
3-Finally, the HUNEC2025 team will work to produce a Preliminary Prototype System of the Chemosensor with Cu(II) ions in AQUEOUS media and optimize the Prototype.
