System description
Dimensionality: D
Sample type: single crystal

Starting materials: pyridine, iodoethylammonium iodide, anhydrous acetonitrile, PbI2, HI

Product: red plate crystals

Description: First, PyrEAI was synthesized by charging a flamed-dried two-neck round bottom flask with pyridine (1.05 equivalent), iodoethylammonium iodide (1.00 equivalent), and anhydrous acetonitrile (which was dried with CaH2 before distillation). The mixture was heated and stirred at reflux for 2 days. The mixture was then cooled to room temperature. The precipitate was isolated by filtration, washed with diethyl ether, and dried. Then, stoichiometric amounts of PbI2 (purchased from Sigma Aldrich) and PyrEAI were added to concentrated stabilized aqueous HI. The concentration of the solution was maintained at 0.25-0.30M of Pb2+. The solution was heated at 140ºC and stirred for an hour. The resulting clear solution was cooled slowly to room temperature.

Method: Single Crystal X-ray Diffraction

Description: Data was collected with a BrukerX8 CCD area detector diffractometer, with Mo Kα radiation (0.71073Å) at 100 K. SAINT and SADABS packages were used for data reduction and absorption corrections, respectively.

Sample type: single crystal

Starting materials: Lead(II) iodide, 2-phenethylamine (PEA), HI, diethyl ether

Product: orange needle-like crystals

Description: a round bottom flask containing ethanol and PEA was cooled to 0 degree C. To it, a stoichiometric amount of concentrated hydroiodic acid was added. After stirring the solution for 1 hour, all volatiles were removed using a rotary evaporator. The remaining solid is PEAI salt. It was washed with diethyl ether and dried under vacuum at 50°C overnight. Stoichiometric amounts of PbI2 and PEAI were added to concentrated stabilized aqueous HI (concentrations of around 0.25-0.30M of Pb2+). The solution was heated and stirred at 140ºC for an hour, and the clear solutions cooled slowly to room temperature.

Method: Single Crystal X-ray Diffraction

Description: Data was collected with a BrukerX8 CCD area detector diffractometer, with Mo Kα radiation (0.71073Å) at 100 K. SAINT and SADABS packages were used for data reduction and absorption corrections, respectively.

System description
Dimensionality: D
Sample type: film

Starting materials: N/A

Description: Thin films were prepared by dissolving (PipEA)[PbI4] (0.50M) in DMF and was spin-coated onto glass substrates at 3000 rpm for 30 s. The films were then heated to 130ºC for 10 minutes.

Method: steady-state PL spectroscopy

Description: Excitation at 405 nm. Data was collected with a Horiba Fluoromax-3 spectrometer with a 0.5nm wavelength resolution.

Extraction method: Engauge Digitizer
