项目摘要

Novel silicon polymers were synthesized and their functionality was examined.1) Sonogashira coupling of diethynylsilanes with dibromoarenes was found to compete with the hydrolytic desilylation to give polymers with highly extended x-conjugated units. The degree of extension of the π-conjugated system was controlled by the amount of water added in the solvent. The resulting polymers were applicable to hole-transporting materials for multi-layered electroluminescence (EL) device systems, whose functionalities were tunable by the degree of extension of the π-conjugated system in the polymers.2) Poly(silylenephenylene)s bearing fluorophores as the pendant groups were synthesized. They were usable for patterning of the PL images in the solid state and ion-sensing in the solution phase. We also found that poly(silylenephenylene)s with cyanophenyl substituents were converted to patterned ceramics films when their spin-coated films were photolyzed in air through photo masks, then heated at high temperature in inert atmospheres.3) Polymers with silole units in the backbone were synthesized and their applications to hole-transporting materials for multi-layered EL device systems were studied. It was also found that the electronic states of the silole-containing polymers were controlled by introduction of Fe (0) coordination on the silole, which affected the conducting properties of the polymers in the doped sates.4) Polymers with alternating silaylene-oligothienylene units were synthesized and their applications to EL devices were examined. It was found that these polymers with long oligothienylene units exhibited not only hole-transporting properties but also electroluminescence in the double-layered EL devices. They also turned out to be usable as active materials for thin film transistors (TFT).5) Energy transfer between π-conjugated systems linked by a silicon bridge in the photo excited states was studied.

合成了新型硅聚合物，并对其功能进行了研究。1)发现二乙基硅烷与二溴芳烃的Sonogashira偶联反应与水解脱硅反应相竞争，得到具有高度扩展的x共轭单元的聚合物。溶剂中水的加入量决定了π共轭体系的延伸程度。所得聚合物可作为多层电致发光（EL）器件体系的空穴传输材料，其功能可通过聚合物中π共轭体系的扩展程度来调节。2)合成了含荧光基团的聚硅氧烷。它们可用于固态PL图像的图像化和溶液阶段的离子传感。我们还发现，带有氰基取代基的聚硅烯-苯基在空气中通过光掩膜进行光解，然后在惰性气氛中进行高温加热，将其自旋涂覆薄膜转化为图案陶瓷薄膜。3)合成了以硅孔单元为骨架的聚合物，研究了其在多层电致发光器件体系中作为空穴传输材料的应用。通过在硅孔上引入Fe(0)配位，控制了含硅孔聚合物的电子态，从而影响了掺杂态聚合物的导电性能。4)合成了具有硅烯-低聚乙烯交替单元的聚合物，并对其在电致发光器件中的应用进行了研究。结果表明，这些具有长聚乙烯单元的聚合物不仅具有空穴传输特性，而且在双层电子发光器件中具有电致发光特性。它们也被证明可用作薄膜晶体管（TFT）的活性材料。5)研究了硅桥连接π共轭体系在光激发态下的能量传递。
