N，N '-双辛基苝二酰亚胺（PDI）在1，7-位上被不同结构的三噻吩官能化，得到三种相同分子量的新的给体-受体（D-A）化合物。噻吩单元在其自身内和朝向PDI核的不同共轭长度、排列和连接对D-A化合物的光学、电子和光化学性质具有强烈影响。就像拼图拼在一起，得到不同的图片，三噻吩连接到PDI，以实现不同的颜色。这些对调节颜色和能级的见解可以为定制发色团以适应其所需的应用开辟新的可能性，例如，有机光致发光器件或有机场效应晶体管。
N,N'-bisoctylperylene diimides (PDIs) have been functionalized in the 1,7-position with terthiophenes of varying architecture giving three new donor-acceptor (D-A) compounds of the same molecular weight. Different conjugation lengths, arrangements, and connections of the thiophene units within themselves and toward the PDI core have strong effects on the optical, electronic, and photochemical properties of the D-A compounds. Like jigsaw pieces joined together to give different pictures, the terthiophenes are linked to PDIs to achieve different colors. These insights into tuning color and energy levels can open new possibilities for tailoring chromophores to their desired applications, e.g., organic photovoltaics or organic field effect transistors.
