Imide-based Subphthalocyanines (SubPcs) is gaining momentum as non-fullerene acceptors in organic solar cells (OSCs). Herein we report the synthesis, characterization, and photovoltaic performance of Perylenemonoimide (PMI)-SubPc conjugates in which the PMI is linked to the SubPc core by either alkynes or direct C-C bond. These derivatives are prepared via palladium-catalyzed cross-coupling reactions. The introduction of PMI units results in a red-shifted absorption, which can be described as the combination of the absorption properties of both SubPc and PMIs fragments. The absorption spectra are thus mainly composed of two transitions, one derived from the SubPc Q-band and the other from transitions within the PMI moieties. These PMI-SubPc systems exhibit moderate acceptor properties and therefore their use as non-fullerene acceptors in bulk-heterojunction organic solar cells is briefly explored.

基于酰亚胺的亚酞菁 (SubPcs) 作为有机太阳能电池 (OSC) 中的非富勒烯受体正在获得发展势头。在此，我们报告了苝单酰亚胺 (PMI)-SubPc 缀合物的合成、表征和光伏性能，其中 PMI 通过炔烃或直接 CC 键连接到 SubPc 核心。这些衍生物是通过钯催化的交叉偶联反应制备的。PMI 单元的引入导致吸收红移，这可以描述为 SubPc 和 PMI 片段吸收特性的组合。因此，吸收光谱主要由两个跃迁组成，一个来自 SubPc Q 波段，另一个来自 PMI 部分内的跃迁。
