Starting materials: 2TI, SnI2, HI, H3PO2, IPA
Product: Single crystals of 2D tin halide perovskites. Thin flakes were then exfoliated from the single crystals.
Description: Single crystals synthesized by slow cooling method. Growth solution prepared with 0.03mmol 2TI, 0.03mmol SnI2, 0.1mL HI, 0.05mL H3PO2, and 0.4mL IPA in a sealed glass vial and placed in a muffle furnace and heated until completely dissolved. Solution cooled to room temperature at a rate of 2°C/hour. Crystals were then dried and stored in a nitrogen glove box.
Method: Single crystal X-ray diffraction
Description: PXRD performed by Bruker D8 Advance instrument scanning at 0.02° per step with a copper target. All single crystals were analyzed using a Bruker AXS D8 Venture diffractometer with a high-intensity diamond Cu/Mo hybrid dual-microfocal x-ray tube. All data collecting and processing was completed using APEX4 software. Full matrix least squares against F2 method was used for further refinement of structures.
