加快印刷有机电子设备向可再生材料和可持续工艺的转变对于绿色循环经济至关重要。目前，具有竞争性能的有机器件的制造与具有大量碳排放的有毒石化溶剂有关。在这里，我们表明，从可再生原料中获得的萜烯溶剂可以替代不可再生的对环境有害的溶剂，用于生产高效有机光伏 (OPV)、发光二极管 (OLED) 和场效应晶体管 (OFET)，且具有同等性能。使用汉森溶解性墨水配方框架，我们识别了各种萜烯溶剂系统，并研究了最佳电荷传输所需的有效成膜和干燥机制。这种方法对于 OPV、OLED 和 OFET 中最先进的材料是通用的。我们创建了一个用于选择绿色溶剂的交互式库，并通过 OMEGALab 网站公开提供。作为潜在的负碳溶剂，萜烯为高效、大面积和稳定的有机电子器件开辟了一种独特且通用的方法。
Accelerating the shift towards renewable materials and sustainable processes for printed organic electronic devices is crucial for a green circular economy. Currently, the fabrication of organic devices with competitive performances is linked to toxic petrochemical-based solvents with considerable carbon emissions. Here we show that terpene solvents obtained from renewable feedstocks can replace non-renewable environmentally hazardous solvent counterparts in the production of highly efficient organic photovoltaics (OPVs) light-emitting diodes (OLEDs) and field-effect transistors (OFETs) with on-par performances. Using a Hansen solubility ink formulation framework, we identify various terpene solvent systems and investigate effective film formation and drying mechanisms required for optimal charge transport. This approach is universal for state-of-the-art materials in OPVs, OLEDs and OFETs. We created an interactive library for green solvent selections and made it publicly available through the OMEGALab website. As potential carbon-negative solvents, terpenes open a unique and universal approach towards efficient, large-area and stable organic electronic devices.
