Redox active organo silica based on phenothiazines

吩噻嗪的氧化还原性质易于调节，是开发新型功能电子材料的理想候选者。本项目的目的是合成并表征带有活性基团的吩噻嗪类化合物，用于将它们接枝到多孔材料上。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)，它可以通过模板定向的(RO)3Si-xSi(OR)3型倍半硅氧烷的缩合来获得。因此，X也可以是吩噻嗪。此外，还将研究阳离子吩噻嗪在阴离子官能化PMO孔表面的静电拴接。将详细研究作为接枝过程的产物的自由吩噻嗪和有机/无机杂化材料的光和电化学性质，以及它们与孔中存在的电子受体的相互作用。

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.
