The ability to tune the dye structure synthetically has been crucial in the development of materials with tailored properties for given applications. In this contribution, a series of discrete molecules are reported, which are constructed from the perylene diimide (PDI) chromophore and three dyes, namely thienyl diketopyrrolopyrrole (DPPTh2 ), pyridyl diketopyrrolopyrrole (DPPPyr2 ), and thienoisoindigo (TII). Through the choice of dye molecule and linking of the dye and PDI through conjugated acetylene bridges, the light-harvesting characteristics can be engineered to exhibit optical absorption in the range 300-900 nm. Each molecule shows ambipolar redox behavior, leading to unique electrochromic behavior.

含Per二酰亚胺材料的近红外吸收光谱工程。

对于给定的应用，合成调整染料结构的能力对于开发具有定制性能的材料至关重要。在该贡献中，报道了一系列由molecules二酰亚胺（PDI）生色团和三种染料构成的离散分子，即噻吩基二酮吡咯并吡咯（DPPTh2），吡啶基二酮吡咯并吡咯（DPPPyr2）和噻吩并靛蓝（TII）。通过选择染料分子并通过共轭乙炔桥将染料与PDI连接，可以设计光收集特性，以显示300-900 nm范围内的光吸收。每个分子显示双极性氧化还原行为，从而导致独特的电致变色行为。
