modified fluorene polymers tethered to the heterogeneous types of the fluorescent dyes at the cardo carbon for obtaining the dual‐emissive solid materials. A series of the alternating fluorene copolymers modified with pyrene or 9,10‐diphenylanthracene and BODIPY at the cardo carbon based on the red‐emissive donor–acceptor structure were prepared, and their characteristics were examined. From the measurements
我们报道了在碳素碳上与异质类型的荧光染料束缚的改性芴聚合物的合成,从而获得了双发射固体材料。制备了一系列基于红色发射供体-受体结构的,在the碳上用pyr或9,10-二苯基蒽和BODIPY改性的交替芴共聚物,并研究了它们的特性。通过光学性质的测量,评估了能量转移效率。总之,观察到侧链之间以及从侧链到主链的可变能量转移效率。结果表明,能量转移效率在很大程度上取决于能量供体的类型和溶液或薄膜中的检测条件。此外,发现心碳芴单元可以在冷凝状态下有助于抑制能量转移。最后,在薄膜状态下获得了双发射聚合物。就我们所知,这是第一个例子,不仅提供有关染料分子与聚合物主链之间通过Cardo结构进行能量转移的系统信息,而且还展示了具有双重结构的基于聚合物的光学材料发射特性。©2015 Wiley Periodicals,Inc.
