Novel class of mesoporous films of transparent conducting oxides for optoelectronic devices with enhanced performance

将合成具有成熟介孔结构的透明导电氧化物（掺杂铟、锡和锌基金属氧化物）的大表面积互连网络。这种新型材料将具有定制的结构特性（电导率，结晶度和晶体互连性），可控制的纹理特性（3d介孔提供大的可达表面积，最佳孔径）和高光学透明度的独特组合。采用合适的结构导向剂和合成后处理可以控制介孔TCO膜的结构和织构性能。除了基于铟的tco，开发基于锡和锌氧化物的更便宜的tco将是该项目的重点。研究开发的介孔多晶TCO体系的电导率和光学性质的机理。光电活性客体将被纳入介孔TCO薄膜中，即电致变色活性酞菁分子和金属氧化物层（如WO3和V2O5），电致发光的联吡啶钌化合物和金属氧化物层（如ZnO和TiO2），旨在开发新型高效染料敏化太阳能电池，电化学发光传感器和电致变色器件。

Large surface area interconnected networks of transparent conducting oxides (TCO) (doped indium, tin and zinc-based metal oxides) with developed mesoporous architecture will be synthesized. This novel type of materials will possess unique combination of tailored structure properties (electric conductivity, crystallinity and crystallites interconnectivity), controlled texture properties (3D-mesoporosity providing large accessible surface area, optimum pore size) and high optical transparency. Structure and texture properties of mesoporous TCO films will be controlled by using suitable structure-directing agents and post-synthetic treatment. Aside from the indium-based TCOs, development of cheaper classes of TCOs based on tin and zinc oxides will be in the focus of the project. Mechanisms of electrical conductivity and optical properties of developed mesoporous polycrystalline TCO systems will be studied. Optoelectronically active guests will be incorporated into the mesoporous TCO films, namely electrochromically active phthalocyanine molecules and layers of metal oxides such as WO3 and V2O5, electroluminescent ruthenium bipyridyl compounds and photoactive layers of metal oxides such as ZnO and TiO2 with the aim to develop new types of highly efficient dye-sensitized solar cells, electrochemoluminescent sensors and electrochromic devices.
