通过Heck偶联反应合成了含[2.2]对环芳和芴单元的新型空间π共轭聚合物。聚合物6a-c在普通有机溶剂中具有良好的溶解性和良好的热稳定性。所有的聚合物6a-c都表现出明亮的蓝光发射，在溶液中具有67 - 72%的高光致发光（PL）效率。由循环伏安图估算聚合物6a的HOMO和LUMO能级。成功地制造了使用含环凡聚合物的第一种有机电致发光（EL）材料，并在500 nm左右显示出蓝绿色光。
Novel through-space π-conjugated polymers having [2.2]paracyclophane and fluorene units were synthesized by the Heck coupling reaction. The polymers 6a−c possess good solubility in common organic solvents and good thermal stability. All of the polymers 6a−c exhibited bright blue emission with high photoluminescence (PL) efficiencies of 67−72% in solution. The HOMO and LUMO energy levels of the polymer 6a were estimated from the cyclic voltammogram. The first organic electroluminescence (EL) material using a cyclophane-containing polymer was successfully fabricated and showed a bluish-green light at around 500 nm.
