System description
Dimensionality: 2D
Sample type: single crystal

Starting materials: PbI2 (Johnson Matthey, 976204), PbO (Ferak 01-881), hydroiodic acid 57% (Merck 341), H3PO2 50% (Fluka 9421), benzylamine (Fluka 13180)

Product: Orange plate crystals

Description: To prepare C6H5CH2NH3I, treat benzylamine with aq.HI 57% in the presence of H3PO2 and recrystallize the precipitate from acetonitrile. Treat C6H5CH2NH3I and PbI2 in molar ratio 2:1 in CH3CN or DMF to obtain small crystals. Dissolve C6H5CH2NH2 (107 mg, 1 mmol) and PbO (111.5 mg, 0.5 mmol) in aq. HI (57%) in the presence of H3PO2 at reflux temperature to obtain large crystals. Slowly cool the solution and obtain the crystals several hours later, filter and dry in air.

Method: X-ray diffraction

Description: Collect on a Crystal Logic dual goniometer using graphite monochromated MoKa radiation. Unit cell dimensions were determined and refined by using the angular setting of 24 automatically centered reflections in the range 11° < 29 < 24°. Intensity data were recorded using a Theta-2theta scan. Refer to page 1406 for details.

Starting materials: (PMA)2PbI4 crystals, DMF, glass substrates

Product: Thin-film on glass

Description: Dissolve the 2D single crystals into DMF at a concentration 6%∼10% relative to the total weight. Spin-coat at 3000 rpm for 30 s on glass substrates. Anneal in air at 100 °C for 10 min before measurement.

Method: Photoluminescence

Description: The photoluminescence spectra were measured using a Horiba-Jobi-Yvon LabRAM ARAMIS system, with a 325 nm He-Cd laser excitation. The laser beam was collimated and focused through a 40X UV objective onto the sample surface at room temperature. Refer to figure 5.
