摘　　要：近年来随着对材料兼顾高性能、柔性、环保、质量轻、低矫顽场、可靠性等诸多要求的不断提高,对传统的陶瓷铁电材料提出了新的挑战。陶瓷材料虽然性能好却含重金属,还存在密度大、重污染、生产耗能高、材料矫顽场高、刚性强等不足。目前陶瓷铁电材料已不能完全满足现代电子信息工业发展对材料的需求,急需寻找新材料去弥补传统陶瓷材料的不足。在此背景下,分子铁电材料由于自身的诸多特点重新受到重视,其质量轻、柔性高、环保、无重金属、能耗低。因此,我们将分子铁电材料与陶瓷铁电材料进行对比研究,借鉴相关研究的新发现、相关理论、重要方法,依托晶体工程和化学多样性为分子铁电材料研究提供有效帮助并构筑分子模型和设计调控结构,以寻求在性能、能耗、环保、柔性等多个角度实现突破,进而合成新型分子铁电材料,为其将来实用化和系统的科学研究提供指导和材料基础。In recent years, along with the requirements of high performance, flexibility, environmental friendly, light weight, low coercive field and reliability, the traditional ceramic ferroelectric material was presented new challenges. The ceramic materials contain heavy metals with large density, environmental toxicity, high energy consumption, high coercivity and strong rigid. Current- ly, ceramic ferroelectric materials cannot fully meet the needs of modem electronic information industry. Therefore, the molecular ferroelectric material is being studied seriously again, due to its many features, such as light weight, flexible, environmentally friendly, free of heavy metals and low energy consumption, and relying on crystal engineering and chemical diversity, which provide effective help for the research of molecule-based ferroelectric materials, and build molecular models and regulate structures to achieve novel molecular ferroelectric materials. Those provide guidance and material foundation for the further scientific research and applications.
