The proposal targets, for the first time, luminescent chemosensors for transition metal containing oxoanions. These include species of biological, environmental and industrial importance, such as molybdate and pertechnetate. The sensor systems will be based on two components which form discrete subunits of the same molecule. 1) specific chelating units for metal ion binding and 2) components capable of signalling the binding by changes in the intensity or frequency of light emission. The subunits will communicate which each other by photoinduced electron or energy transfer. This modular approach facilitates the optimisation of the sensor properties by combinatorial methods.Since the metal binding units will consist of siderophore derivatives, the resulting biomimetic systems should benefit from the unique metal chelating properties of these microbial metal ion sequestering agents. As signalling units, positively charged lumophores will be chosen in order to support the anion detection by electrostatic attraction. The advantages of luminescent signalling are the inherent sensitivity, simplicity and suitability for real-time and real-space monitoring.The metal binding properties as well as the spectroscopic and electrochemical characteristics of the systems will be studied in detail. Once proven, the sensors could have applications in industrial control, environmental monitoring and biochemical research with a potential for rapid and selective in situ measurements.
