About

Ren‑Gen Xiong is a pioneering figure in the field of molecular ferroelectrics, whose work has fundamentally reshaped the search for flexible, high‑performance alternatives to traditional ceramic piezoelectrics. His research centers on designing organic–inorganic hybrid materials that combine structural tunability with exceptional electromechanical properties. Xiong’s landmark 2017 paper, cited over 1,060 times, reported the first organic‑inorganic perovskite ferroelectric with a large piezoelectric response, demonstrating that soft, solution‑processable crystals could rival stiff ceramics like BaTiO₃. This breakthrough opened the door to more flexible mechanical sensors. Building on this, his 2019 study on two‑dimensional layered perovskite ferroelectrics achieved a giant piezoelectric voltage coefficient, a critical parameter for self‑powered sensors in the Internet of Things. That work, with 247 citations, also highlighted the importance of a high Curie temperature for practical device stability. In a related achievement, Xiong’s team created an above‑room‑temperature molecular ferroelectric using cyclopentylammonium‑based compounds, overcoming a major hurdle in bringing molecular ferroelectrics into real‑world applications. Through these contributions, Xiong has established a new design paradigm for lightweight, flexible, and environmentally friendly piezoelectric materials, earning him recognition as a leader in molecular ferroelectrics and smart materials.
