摘　　要：超快二维电子光谱技术在过去二十余年间得到了迅速的发展,并在研究光合作用、光伏材料与低维材料等的激发态布居动力学与相干动力学过程中发挥了重要作用。本综述将首先介绍二维电子光谱在拓展探测窗口与维度方面的技术发展。然后,讨论领域内现存的挑战与未来发展方向:在技术层面,如何降低二维电子光谱的技术门槛以及发展多光谱数据分析程序,是拓展二维电子光谱应用的重要瓶颈问题;在基础研究层面,如何发展新型的二维电子光谱技术,去更好地探测与解析相干调控动力学与极化基元动力学过程,是该领域的另一个关键难题。Since the past two decades,ultrafast two-dimensional electronic spectroscopy(2DES) has made remarkable progress,and it plays a pivotal tool in unraveling population and coherent dynamics in photosynthesis,photovoltaic,and low-dimensional materials.This review presents a comprehensive overview of the progress in 2DES,with a focus on its ability to expand spectral windows and dimensions.Furthermore,it examines the current challenges and future directions of this field.From a technical perspective,a key bottleneck preventing the wide application of 2DES is the need to overcome experimental hurdles and develop sophisticated multispectral data analysis methods.In cutting-edge research,a crucial question centers on the development of novel 2DES techniques to effectively probe and disentangle various processes within coherent dynamics and polaritonic systems.
