Starting materials: Tin(II) oxide (Sigma Aldrich, 97%), hydriodic acid (Sigma Aldrich, 57% w/w in H2O, 99.9%), hypophosphorous acid (Avra, 50% w/w H2O), phenylethylamine (Sigma Aldrich, 99.9%)
Product: (PEA)2SnI4 crystals
Description: Single crystals of (PEA)2SNI4 were synthesized by adding tin (II) oxide (0.6 mmol), hydriodic acid ( 5 mL), and hypophosphorous acid (3 mL) into a sealed vial and heated at 90 ˚C under constant stirring. After tin (II) oxide dissolved in the solution and yielded a dark yellow color, phenethylamine (1.2 mmol) was injected into the sealed vial by a syringe. A brown sheet of crystals of (PEA)2SNI4 produced after the solution was cooled to room temperature. The crystals were then obtained via filtration and were stored in an N2 glove box.
Method: UV-visible absorption
Description: Optical diffuse-reflectance spectra were collected at room temperature using a Shimadzu UV-3600 plus UV-VIS-NIR spectrophotometer. The reflectance spectra were converted to absorbance by using the Kubelka-Munk transformation; (α/S = (1 − R)^2/2R); α is the absorption coefficient, S is the scattering coefficient, and R is the reflectance.

Starting materials: Lead(II) oxide (Sigma Aldrich, 99.9%), decylamine (Sigma Aldrich, 99%), hydriodic acid (Sigma Aldrich, 57% w/w in H2O, 99.9%)
Product: (DA)2PbI4 crystals
Description: (DA)2PbI4 single crystals were synthesized by dissolving lead oxide (0.5 mmol) in 20 mL of hydriodic acid by heating to boiling under constant stirring. To it, 0.5 mmol of decylamine was added. The solution was heated and stirred until the precipitate dissolved completely. Then the solution was allowed to cool naturally to room temperature.
Method: UV-visible absorption
Description: UV-Visible absorbance data were recorded on the transmission mode in Cary Series UV-Vis Spectrophotometer (Agilent Technologies).
Starting materials: lead oxide (10 mmol), hydriodic acid (10 mL), hypophosphorous acid (1.7 mL ), C4H9NH3I, I2
Product: (BA)2PbI4:I2
Description: Single crystals of (BA)2PbI4 were synthesized in a method called acid precipitation. Through constant stirring and heating, lead oxide (10 mmol) was dissolved in a solution that contained hydriodic acid (10 mL) and hypophosphorous acid (1.7 mL). After, C4H9NH3I was added to the mixture, causing the bright yellow solution to change to an orange color precipitate. Continuous heating of the mixture followed until the precipitate was fully dissolved, forming orange crystals at room temperature. The crystals were obtained via filtration and bathed in diethyl ether. Dried (BA)2PbI4 crystals were placed in an open plastic tube which was kept in a closed glass vial containing molecular I2 for 2-3 hours at room temperature.

Method: UV-vis absorption
Description: Optical diffuse-reflectance spectra were collected at room temperature using a Shimadzu UV-3600 plus UV-VIS-NIR spectrophotometer. The reflectance spectra were converted to absorbance by using Kubelka-Munk transformation: (α/S = (1 − R)^2/2R); α is the absorption coefficient, and S is the scattering coefficient R is the reflectance.
