Two kinds of ladder-type conjugated polymers were concisely synthesized by the formation of single-stranded conjugated polymers via Stille cross-couplings, followed by nitrogen-directed electrophilic borylations at electron-rich aromatic rings. The resulting BN-annulated polymers show good film-forming behaviors and high air and thermal stability. Their structurally shape-persistent rigid backbones render them with π-extended conjugation, allowing for efficient light harvesting in the low-energy regions, and emitting strong fluorescence with narrow emission widths.

通过BN环扩扩π型梯形共轭聚合物

通过Stille交叉偶联形成单链共轭聚合物，然后在富电子芳族环上进行氮定向的亲电子硼化反应，简明地合成了两种梯型共轭聚合物。所得的BN环化聚合物表现出良好的成膜性能以及高的空气和热稳定性。它们的结构形状持久的刚性骨架使它们具有π扩展共轭，从而允许在低能量区域有效收集光，并发射具有窄发射宽度的强荧光。
