)hexyl)thiophene and subsequent cleavage of a tetrahydropyranyl group. Acid-catalyzed polycondensations of tetraethoxysilane (TEOS) were carried out in the presence of these polymers to give homogeneous composites with silica. The resulting composite materials were characterized by UV−vis and emission spectra.
进行2-甲氧基-5-(2-乙基己氧基)-对苯二甲撑双(三苯基氯化chloride)与2-甲氧基-5-(2-乙基己氧基)苯-1,4-二甲醛的维蒂希反应,得到聚[2 -甲氧基-5-(2-乙基己氧基)-1,4-亚苯基亚乙烯基](MEH-PPV)在链端用terminated部分终止。聚[3- hexylthiophene-共-3-(6-羟基己基)噻吩] 01用2-溴-3-己基噻吩和2-溴-3-(6-(2-四氢吡喃氧基)己基)区域选择性偶联反应制备噻吩然后切割四氢吡喃基。在这些聚合物的存在下,进行四乙氧基硅烷(TEOS)的酸催化缩聚反应,得到具有二氧化硅的均质复合材料。所得的复合材料通过紫外可见光谱和发射光谱进行表征。
