Can molecular ferroelectrics challenge pure inorganic ones? Zhe-Ming Wang and Song Gao∗ Molecular materials have attracted much attention due to their advantages of easy modification and fabrication, environ-mentally friendly and less energy-cost processing, transparent, light weight, mechanical flexibility and possible multi-functionalities, compared to their counter parts of pure inorganic or metal-lic ones, and many functionalities and properties have been discovered and re-alized inmolecule-basedmaterials [1–4]. Ferroelectrics, as an important class o
