Starting materials: HI, phenylethylamine, PbAc2•3H2O, IPA
Product: yellow crystals
Description: First, PEAI was synthesized by adding HI (48 wt.% in water) to phenylethylamine at a molar ration of 1:1. This was performed at 0º C. Water was evaporated in a hood (at ~100º C) until PEAI crystals formed. Solution then cooled, powder product was filtered, washed with diethyl ether, and dried at 80º C in a vacuum oven for ~24 hours. Next, (PEA)2PbI4 was synthesized. Fluoride-doped tin oxide (FTO) glass substrate was coated with a film of lead acetate by drop-casting PbAc2•3H2O (100 mg/mL). This was dried for 30 minutes at 60º C. The PbAc2 film was placed into PEAI solution in IPA, having various concentrations at room temperature. The lead-coated side was facing down in the vial. After the reaction (~20 hrs), the substrate was removed, dipped into IPA again to remove extra solution, and dried under a stream of N2.
Method: Single Crystal X-ray Diffraction
Description: Single crystal was attached to tip of MiTeGen MicroMount, under a stream of N2 at 100 K. Data was recorded with Bruker Quazar SMART APEXII diffractometer with Mo Kα (λ = 0.71073 Å) radiation.
