Накратко на български
Полиоксометалатите са специални материали, които могат да провеждат ток и да се закрепят върху повърхности за откриване на вещества като нитрити и йодати. Те помагат за разработването на по-ефективни сензори чрез проучване на техните химични и повърхностни свойства.

Final Activity Report Summary - ISOPOLYANIONS (Design of Novel Multi-functional Materials based on Isopolyanions)
Solid state redox active materials, which can be oxidised and reduced, have received little interest over recent years. This is somewhat surprising given the key roles they play in a wide variety of devices, in particular ranging within the field of sensor technology. These solid materials are able to conduct an electric current, due to them possessing two types of conductivities, namely, electronic and ionic. For the successful development of materials, it is vital that several unanswered key research questions be addressed these include: - Can pure and stable redox active solid state materials be attained? - Can they be successfully deposited onto a variety of surfaces so as to attain stable systems? - Can the redox and surface properties of the materials when surface immobilised be probed. - What are the redox and surface properties of these systems? - What are the applications of these systems? This research proposal was concerned with the development of a novel type of redox active material based upon a family of compounds, polyoxometallates. The main findings of this work have been the following: - A range of redox active polyoxometallate systems were synthesised and fully characterised by modern electrochemical and spectroscopic techniques. - The technique of nanoassembly was applied so as to surface immobilise these POMs in an ordered fashion onto a variety of electrode surfaces (i.e. carbon and indium tin oxide). - The redox activity and the surface properties of these surface immobilised systems has been investigated successfully. - The possible employment of these nanoassemblies in sensor technology has been explored with the assemblies showing interaction with nitrite and iodate in solution.

Цел на проекта
This project aims to synthesis and investigate a new range of conducting solid state materials based on inorganic complexes of isopolyanions. These materials play an important role in a range of devices from optical detectors to sensors. They possess two types of conductivity, electronic and ionic which we aim to investigate using a range of electrochemical and surface science techniques. Key research questions such as the mechanism of charge transport within the materials, the effect of pH on both the physical structure and charge transport dynamics and the effect of redox switching on the materials solid state morphology will be answered. Our findings will have an impact on the development of materials for solid state applications. The main objectives are:1. Synthesis and characterisation of novel analytically pure redox active materials;2. The study of charge transport dynamics of surface immobilised materials;3. Elucidation of the materials solid state structure;4. Modelling the effect of protonation on materials solid state structure and charge transport dynamics.These objectives will be achieved using innovations and tasks involving the use of voltammetric and surface techniques. It is hoped that this project will provide the top-class researcher from China the means to acquire new skills/experience which will aid her professional development and support knowledge transfer upon her return to China. Both scientific and complementary training will be provided in order to enhance the researchers experience and to maximise career prospects within her chosen area.
