具有供体-受体(D-A)结构的有机光敏剂(PS)设计中的一个特殊挑战是,它基于试验和错误而不是特定的规则。现在,通过提出两种提高光敏效率的有效策略来应对这些挑战:聚合促进的光敏和D-A奇偶效应。已发现共轭聚合物表现出更高的1 O 2发电效率要比它们的小分子同行高。此外,具有AD结构的PS与具有AD结构的PS相比,具有更高的光敏效率。理论计算表明,通过这些策略可以提高系统间穿越(ISC)的效率。体外和体内实验均表明,所得材料可在图像引导的光动力抗癌治疗中用作光敏剂。这些准则适用于其他聚合物和小分子,以导致新PS的发展。

discrete conjugatedoligomers (Đ = 1.0) using the combination of controlled polymerization and automated flash chromatography is reported. From this two-step process, a series of discrete conjugatedmaterialsfrom dimers to tetradecamers could be isolated in high yield with excellent structural control. Facile and scalable access to monodisperse libraries of different conjugatedoligomers opens pathways
New BN‐embedded, thiophene‐fused, polycyclicaromaticcompounds with planar geometry were designed and synthesized. The molecules showed excellent stability and chemical robustness. Postfunctionalization on this skeleton was demonstrated with a series of electrophilic bromination, palladium‐catalyzed cross‐coupling, and Knoevenagel condensation reactions. The π skeleton remained intact during these
New, biocompatible materials with favorable antibacterial activity are highly desirable. In this work, we develop a unique conjugatedpolymer featuring aggregation‐induced emission (AIE) for reliable bacterial eradication. Thanks to the AIE and donor‐π‐acceptor structure, this polymer shows a high reactive oxygen species (ROS)‐generationability compared to a low‐mass model compound and the common
