Synthesis of self-organizing and immobilizing conjugated polymers and study of the electronic and optoelectronic properties

使用烷氧羰基取代的单体，例如n - boc保护的二溴菲咯啶和合适的共聚物（例如二烷基芴二硼酯），将在金属催化缩聚后制备共轭聚合物。烷氧羰基使该聚合物可溶于普通有机溶剂，适于溶液处理。通过溶液浇铸或旋涂法制备聚合物薄膜后，将其在高温下退火，以便热裂解烷氧羰基。解理后，聚合物能够形成氢桥结构，并增加材料的有序度。固体聚合物薄膜的溶解度大大降低，与衬底的附着力得到改善，可作为光电、发光或电致变色等电子器件的有源元件。将研究固定化聚合物薄膜的光活性和电活性（荧光、电致发光、电致变色和/或光伏性能）。

Using alkoxycarbonyl substituted monomers as for example N-Boc-protected dibromo-phenanthridine and suitable co-monomers (as for example dialkylfluorene diboronester), conjugated polymers will be prepared upon metal-catalyzed polycondensation. The alkoxycarbonyl groups render the polymers soluble in common organic solvents and suitable for solution processing. After the polymeric film is prepared by solution casting or spin-coating, it will be annealed at elevated temperatures in order to cleave the alkoxycarbonyl groups thermally. After cleavage, the polymers are able to form a hydrogen-bridged structure with increased order of the material. Solid polymeric films with strongly decreased solubility and improved adhesion to the substrate are obtained, which might be useful as active components in electronic devices such as photovoltaic, light emitting or electrochromic devices. The photo- and electroactive properties of the immobilized polymeric films (fluorescence, electroluminescence, electrochromism and/or photovoltaic properties) will be investigated.
