Abstract
Hybrid organic-inorganic perovskites(HOIP)have attracted increasing interest in the last decade.While current research in this field focuses on metal halide HOIPs because of their excellent photovoltaic and optoelectronic properties,other hybrid perovskites are also being designed and developed for other properties.Among them,HOIPs bridged by nitrate show structural diversity and a remarkable range of physical properties.In this mini review,we summarize their structural features and rich physical properties including structural phase transitions,ferroelectric,piezoelectric,piezomagnetic and photoluminescencent properties.In addition,the challenges for improving the physical properties achieved by such materials and the space for further development of such materials are also discussed.
