Molecular and macromolecular chiral π-conjugated diketopyrrolopyrrole (DPP)–helicene derivatives were prepared and their chiroptical properties examined experimentally and theoretically. Exciton coupling leads to red and near-infrared circularly polarized absorption and luminescence arising from the achiral DPP units in the helical environment, highlighting an interesting synergy between the chiral helicene and the organic dye.

二酮吡咯并吡咯-螺旋烯衍生物中的激子耦合导致红色和近红外圆偏振发光†

制备了分子和大分子手性 π-共轭二酮吡咯并吡咯 (DPP)-螺烯衍生物，并通过实验和理论检验了它们的手性光学性质。激子耦合导致螺旋环境中的非手性 DPP 单元产生红色和近红外圆偏振吸收和发光，突出了手性螺旋烯和有机染料之间有趣的协同作用。
