Objective
The scientific objectives of the research activities fall within the field of fundamental interdisciplinary science and combine the basic ideas of semiconductor physics, colloid chemistry and the photo- and electrochemistry of organic molecules. The project aims at focusing the efforts of 5 research groups with complementary competence in their respective research fields and at gathering multidisciplinary and complementary expertise in chemical engineering and investigation of nanosize composites based on semiconductor colloidal nanoparticles and supramolecular organic compounds.
The expected results are connected with the fabrication and characterisation of heterosupramolecular nanostructures comprised of semiconductor nanocrystals and organic tetrapyrrole molecules. The physico-chemical mechanisms of photoinduced processes of charge separation/recombination will be evaluated for these assemblies capable of transforming the captured light energy into electric energy via photo-induced charge transfer processes. The creation of these novel types of organic/inorganic nanocomposites will have future impact on applications in molecular electronics, photovoltaics and new materials for photonics.
The main Project objectives are:
Creation of novel heterogeneous nanosized assemblies of semiconductor-organic tetrapyrrole compounds in solutions, films and on surfaces, based on semiconductor thiol-stabilised CdTe and TOPO (trioctylposphin oxide)-stabilised CdSe/ZnS nanocrystals surfacely anchored by organic molecular or supramolecular species.
Determination of the structure - function relationship of the heterogeneous semiconductor nanocrystal/organic molecule assemblies by steady-state and time resolved optical methods, near field scanning optical microscopy (SNOM), spatially resolved fluorescence measurements and single molecule/single particle microscopy and spectroscopy.
Investigation of the evolution of the electronic states of adsorbed organic molecules and chemical tunability of electronic, optical and redox properties of interacting components under the conditions of tunable size dependent quantization of semiconductor quantum dot nanocrystals.
Light-harvesting dynamics, electron/hole transport directionality, and charge separation/stabilisation efficiency depending on the quantum size effects and molecular electronic states in comparison of bulk material and under single molecule/single particle conditions.
Identification and selection of photostable heterogeneous nanosized assemblies with controllable light-collection properties, effective vectorial photoinduced charge transfer and temporal separation/stabilisation for possible applications in nanomaterial technologies (future optically or electronically controlled nano-devices).
Design and investigation of nanometer-scaled prototype photo-electric cell on a nanometer scale.
