 Abstract: Halide perovskites are being in the focus of diverse research fields due to their attractive physicochemical properties. Herein, we present a strategy to prepare highly crystalline bismuth-based halide perovskite disk, polystyrene nanospheres incorporated hybrid material and porous halide perovskite. After a proper surface modification of polystyrene, the halide perovskite was grown and crystallized around the sulfonated polystyrene via a facile solution processed synthesis and rapid solidification. By tuning the particle size of sulfonated polystyrene, a range of lead-free hybrid materials was prepared. All the hybrid materials have good visible light absorption with an optical band gap of around 2.6 eV and variable photoluminescence properties. The incorporated sulfonated polystyrene could enhance the stability of halide perovskite in high humidity environments. Additional porous functionality could be brought to the halide perovskite materials through selective leaching of sulfonated polystyrene.
