采用Suzuki-Miyaura缩聚和Friedel-Crafts环化法制备了结构完美的螺旋桥梯形聚对苯醚，在光致发光（PL）和电致发光（EL）发射光谱中显示蓝色荧光。该聚合物无酮性缺陷，在空气中110℃退火24小时后表现出优异的热稳定性和颜色稳定性。
Structurally perfect spiro-bridged ladder-type poly(p-phenylene)s, which show blue fluorescence in the photoluminescence (PL) and electroluminescence (EL) emission spectra, are prepared by Suzuki-Miyaura polycondensation and Friedel-Crafts cyclization. The polymers are free of ketonic defects, exhibiting excellent thermal and color stability upon annealing in air at 110 degrees C for 24 h.
