  Synthesis of a Double Spiro-Polyindenofluorene with a Stable Blue Emission

  摘要：

  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.

  具有邻-碳环笼的三联苯环的平面性：打开基于分子内电荷转移的发射†

  摘要：

  为了阐明平面度和分子内电荷转移（ICT）之间的关系，合成了两个具有完全异形或平面苯环的邻位三联苯环的邻邻碳烷基化合物（TCB和FCB）。尽管两种化合物的发射光谱在298或77 K的溶液中均处于薄膜状态并呈现出有趣的双发射模式，但扭曲的TCB大多显示出局部激发发射，而平面FCB则显示出与ICT跃迁相对应的强发射。有趣的是，基于三联苯的邻苯二甲醛的发射效率和辐射衰减常数通过增加三联苯基的平面度，逐渐增强了-碳硼烷基化合物。这些结果证明了在邻-甲硼烷取代的化合物中，附加的芳基的平面度与基于ICT的辐射衰减之间存在很强的关系。
