Final Activity Report Summary - BIOPOLTRONIC (Development and characterisation of new semi-conducting polymers soluble in environmental-friendly solvents for self-assembled nanostructures ...)
The main objective of the project was to develop, through transfer of knowledge, competences and know-how, novel poly(p-phenylene vinylene) derivatives soluble in environmentally-friendly solvents as for example water and/or alcohols and to evaluate these materials for organic device applications.
The main conclusions of the work carried out during the course of the project were the following:
- A new successful protocol for the preparation of new amide functionalised PPVs which have not been described yet via post-functionalisation for which an evaluation towards a patent application is ongoing. This new method opens the way to the preparation of new materials which could find potential applications as bio- or chemo-sensors, but also as material for solar cells and OLEDs, and water-soluble materials.
- Also, the suitability of advanced scanning probe techniques to perform nanoscale electrical characterisation of organic materials and blends for organic devices has been demonstrated. Beyond conventional AFM based morphological investigations likely to indirectly foresee properties of blends, EFM and C-AFM demonstrated real ability to yield further electrical characterisation of the structures.
- The most promising results were obtained with C-AFM. This method was shown to provide not only high-resolution 2D mapping of the electrical properties, but proposed additional key features such as local spectroscopy (I-V profiles). Ultimately, the objective will be to make C-AFM a reliable method for routine nanoscale electrical investigations in organic electronics.
