[反应：见正文]合成了一种新型的含双螺蒽结构的聚茚并芴。通过热处理和空气中的光照射研究了聚合物的光谱稳定性。该聚合物的EL光谱显示出对人眼的增强的灵敏度和作为蓝色发光材料的良好色纯度。
[reaction: see text] A novel polyindenofluorene containing a double spiro-anthracene structure with solublizing alkyl groups was synthesized. Enhanced spectral stability of the polymer was investigated by heat treatment and photoirradiation in air. The EL spectrum of the polymer showed an enhanced sensitivity to the human eye and good color purity as a blue-emitting material.
