英文摘要： Ionic liquids have regarded as “green” due to their unique solvent properties. They have showed widely application potential in various fields such as biocatalysis, organic synthesis, clean energy, extraction and separation. Their potential ecotoxicity and biodegradation, design and synthesis of environmentally friendly ionic liquids have gradually attracted great attention. In this project, a series of cholinium ionic liquids are synthesized via simple acid-base neutralization from renewable raw materials. Maize, which is a major field crop, is cultured in hydroponic and soil media respectively for investigation of the effects of cholinium ionic liquids on tissue damage, photosynthetic characteristics and active oxygen metabolism. At the same time, the effects of traditional imidazolium and pyridinium ionic liquids on maize are also studied for a good knowledge of quantitative structure-activity relationships between toxicity and different ions components. In addition, differential proteomics is performed to reveal the internal mechanism of ionic liquids on maize growth.
