The recently discovered gas-induced formation/transformation (GIFT) of organic–inorganic halide perovskites (OIHPs) represents unprecedented phenomena. The GIFT phenomena have not only revealed surprising properties of the fascinating OIHP materials but also showed tremendous promise in various applications, including solar cells, optoelectronics, sensors, and beyond. After briefly reviewing recent progress in the exploration and understanding of GIFT, a perspective on the future research directions in this area is provided herein. Also provided is a discussion on the significance of future mechanistic studies in unraveling the rich chemistry and materials science underlying GIFT and in exploring more potential applications.
