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.

使用烷氧基羰基取代的单体如例如N-Boc保护的二溴菲啶和合适的共聚单体（如例如二烷基芴二硼酸酯），将在金属催化的缩聚后制备共轭聚合物。烷氧基羰基使聚合物可溶于普通有机溶剂中并适合于溶液加工。在通过溶液浇铸或旋涂制备聚合物膜之后，将其在升高的温度下退火以热裂解烷氧基羰基。裂解后，聚合物能够形成氢桥连结构，材料的有序性增加。获得了具有显著降低的溶解度和改善的对基底的粘附性的固体聚合物膜，其可用作电子器件如光伏器件、发光器件或电致变色器件中的活性组分。将研究固定化聚合物膜的光活性和电活性性质（荧光、电致发光、电致变色和/或光伏性质）。
