Starting materials: HI, HA (C6H13NH3), Et2O, PbI2
Product: Powder of (C6H13NH3)2PbI4
Description: Prepare hexylammonium iodide salts via neutralization of HI with HA. Remove unreacted species by evaporation. Purify product by recrystallization in minimal diethyl ether/excess hexane and isolate via vacuum filtration. Prepare films by spin-coating or drop-casting solutions (prepared by dissolving HAI and PbI2 powders at a 2.5:1 molar ratio in a 1:0.34 volume ratio mixture of THF and methanol). To prepare powder for XRD, drop-cast thin film from 200 mg/mL solutions and anneal at 70 °C for 15 min.
Method: Powder X-ray diffraction
Description: Bruker X-ray D8 Advance diffractometer with Cu Kα1,2 radiation (λ = 1.541 Å). Spectra were collected with an angular range of 5 < 2θ < 60° and step size of 0.01022 ° over 60 minutes. Rietveld analysis was carried out using the TOPAS program. Low-temperature measurements were made on cooling between 300−12K using an Oxford Cyrosytem PheniX stage.
