Organic-inorganic hybrid perovskites (OIHPs) have attracted enormous interests as a next-generation semiconductor owing to their attractive features. However, there is a limited understanding regarding the basic features of OIHPs with reduced structural dimensionality such as nanocrystals, nanowires and nanoplates. The lack of understanding is attributed to the lack of various synthetic strategies for various OIHP nanostructures. Here, we report a novel synthetic method which employed block copolymer micelles as scaffolds. We found that block copolymer reverse micelles effectively work as precursor reservoirs and maintain their structures during the crystallization of OIHP nanocrystals. Moreover, by controlling the thermodynamic and kinetic parameters related to the micelle disassembly, various OIHP nanostructures including diffusion-limited products, anisotropic nanowires and micron-sized nanoplates can be obtained. |
