Ortho-bridged perylene diimide dimer and preparation method thereof as well as application thereof in organic photovoltaic devices

The invention provides an ortho-bridged perylene diimide dimer (formula I), a preparation method and an application thereof in the organic photovoltaic field. The invention further relates to an organic solar cell of the compound and a preparation method of the organic solar cell. Compared with a PDI monomer molecule, a formed twisted dimer structure is capable of effectively weakening excessive aggregation among PDI molecules, so that the phase size is reduced. Meanwhile, by virtue of ortho-bridging, the deformation of a PDI inner core caused by waist bridging can be avoided, so that certain planarity and relatively strong pi-pi accumulation can be maintained, and relatively high electronic mobility can be obtained. The PDI dimer is taken as a receptor material and is combined with an electron donor polymer so as to prepare the organic solar cell, so that very high photoelectric conversion efficiency is realized.

Solution-processable tetrazine and oligothiophene based linear A-D-A small molecules: Synthesis, hierarchical structure and photovoltaic properties

A series of high coplanar alternative linear small molecules with acceptor-donor-acceptor (A-D-A) structure containing electron-accepting tetrazine (Tz) moiety and electron-donating oligothiophenes (OTs) moiety, alkylated thiophene attached to both sides of the Tz moiety were designed and synthesized. The influences of varied oligothiophene length on small molecules' optical and electrochemical properties, crystallization, self assembling morphology in blend film with (6,6)-phenyl-C61-butyric acid methyl ester (PC61BM), and photovoltaic properties for the application as donor materials in organic solar cells (OSCs) were studied. The optical and electrochemical properties of small molecules showed that the HOMO and LUMO energy levels were determined by the number of OTs moiety and electron-accepting ability of Tz in the alternative small molecules, respectively. Meanwhile, the varied OT moieties can significantly affect the hierarchical structures when mixed with PC61BM. The molecule with intermediate conjugate moity length showed the highest ordering in its crystalline state, as revealed by differential scanning calorimetry (DSC) and X-ray diffraction experiments, and best photovoltaic properties when blended together with PC61BM or (6,6)-phenyl-C71-butyric acid methyl ester (PC71BM) as active layer in photovoltaic devices. The results indicate that hierarchical structures controlled by adjusting the conjugate moity length of small molecules is an effective way to improve the performance of OSCs. The photovoltaic device based on TT(HTTzHT)2:PC71BM with 1% DIO additives showed the best performance, with a Jsc of 7.87 mA/cm2 and a PCE of 3.24%.
