摘要：21世纪在光子技术领域中操控光子已成为核心的研究内容。胶体光子晶体因其特殊的周期结构而具有光子禁带的特性,从而可以对特定频率的光进行调控,其应用涵盖了光、电、催化、传感、显示、检测等众多领域,为光功能材料的结构设计和性能优化提供了参考依据。本文主要从两个方面阐述近年来胶体光子晶体对光的调控作用与应用,一方面,光子晶体的光子禁带受外界环境刺激下的调控,其核心是在光子晶体中填充响应性的材料,从而引起光子晶体晶格常数或折光指数的变化,这在化学及生物传感器技术领域有着广阔的应用前景;另一方面,光子晶体对嵌入在其中的发射物质的光学行为能实现有效的控制,这将有力地推动光学器件的发展。文章最后还对胶体光子晶体今后的发展进行了展望。

摘要：Introducing liquid-crystalline small-molecule donors(SMDs)into binary systems based on the strong intermolecular interactions of SMDs is a facile and effective strategy to tune the active layer morphology and improve the performance of organic solar cells(OSCs).Contrary to conventional understanding,this research proposes a new strategy for ternary OSCs implicating that"weakly crystalline materials can also optimize the morphology of the active layer and improve the OSCs performance".Herein,we designed and synthesized two liquid-crystalline SMDs,Z1 and Z2,based on benzodifuran(BDF)*** amorphous Z2-incorporated ternary devices present an unexpectedly improved power conversion efficiency(PCE)>18%with good *** contrast,the highly ordered Z1-based ternary devices possess a significantly depressed *** characterizations reveal that the Z2-based ternary blend films possess improved miscibility and efficient charge *** novel strategy for the selection of the third component is significant for the fabrication of high-efficiency ternary OSCs.
