The redox properties phenothiazines can easily be modulated, which makes them ideal candidates for developing novel functional electronic materials. The aim of this project is the synthesis and spectroscopic Characterization of phenothiazines bearing reactive group for grafting them onto porous materials. To realize this, we will use so-called periodically structured mesoporous organo silica (PMO), which are accessible by the template directed condensation of silsesquioxanes of the type (RO)3Si-XSi(OR)3. Hereby X can be a phenothiazinylene, too. Additionally the electrostatic tethering of cationic phenothiazines onto the pore surfaces of anionically functionalized PMOs will be investigated. The photo- and electrochemical properties of the free phenothiazines and of the organic/inorganic hybridmaterials which will be the products of the grafting process will be investigated in detail as well as of their interaction with electron acceptors being present in the pores.

吩噻嗪类化合物的氧化还原性质易于调控，是开发新型功能电子材料的理想材料。本课题的目的是合成并表征带有反应性基团的吩噻嗪类化合物，并将其接枝到多孔材料上。为了实现这一点，我们将使用所谓的周期性结构的介孔有机二氧化硅（PMO），其可通过（RO）3Si-XSi（OR）3型倍半硅氧烷的模板定向缩合来获得。因此，X也可以是亚吩噻嗪基。此外，将研究阳离子吩噻嗪到阴离子官能化的PMO的孔表面上的静电束缚。的光和电化学性能的自由吩噻嗪和有机/无机hybridmaterials，这将是接枝过程的产物将被详细研究，以及它们与电子受体的相互作用存在于孔。
