Starting materials: PbI2, toluene, butyric acid, butylamine, butylammonium iodide
Product: Powder film on glass substrate
Description: PbI2, butyric acid, toluene, and butylamine were mixed in a capped flask. Separately, butylammonium iodide was dissolved in toluene with butylamine and butyric acid. The two solutions were combined and stirred until an insoluble yellow solid precipitated. The solid was removed by centrifuging at 6000 rpm for 3 minutes. The yellow solid was redispersed in toluene and centrifuged a second time, to produce the final products. The paintlike paste was then deposited on a glass substrate. A Pasteur pipette was used to spread the paste over the surface and was then allowed to dry.
Method: Diffuse reflectance spectra
Description: Diffuse reflectance spectra were measured in a Shimadzu UV 2450 instrument. A Ba2SO4 powder palette was the reference used. The reflectance was converted to absorbance.

Method: Photoluminescence spectra
Description: A Horiba-Jobin Yvon Fluorolog-3 instrument was used on the powder films to measure photoluminescence spectra. Excitation was perpendicular to the sample and emission was collected at an angle of ~15 degrees. The data was corrected according to the lamp and detector details by using algorithms from the equipment software.

Starting materials: PbI2, toluene, butyric acid, butylamine, butylammonium iodide, anhydrous acetonitrile
Product: Thin film on glass substrate
Description: PbI2, butyric acid, toluene, and butylamine were mixed in a capped flask. Separately, butylammonium iodide was dissolved in toluene with butylamine and butyric acid. The two solutions were combined and stirred until an insoluble yellow solid precipitated. The solid was removed by centrifuging at 6000 rpm for 3 minutes. The yellow solid was redispersed in toluene and centrifuged a second time, to produce the final products. The solid material was dissolved in acetonitrile to a desired concentration and then was spin-coated onto a glass substrate at 3000 rpm for 30 seconds.
Method: UV-vis absorption
Description: An Agilent Carry 60 UV-vis instrument was used in transmission mode to measure the absorbance. A blank glass substrate was used as the baseline.

Starting materials: PbI2, toluene, butyric acid, butylamine, formamidinium acetate
Product: Powder film on glass substrate
Description: PbI2, toluene, butyric acid, and butylamine were mixed in a capped flask. Separately, formamidinium acetate was dissolved in toluene and butyric acid. The solutions are combined and stirred until a red solid precipitated. The solid was removed by centrifuging at 6000 rpm for 3 minutes. It was then re-dispersed in hexane and centrifuged again to obtain the final paintlike paste. The paintlike paste was then deposited on a glass substrate. A Pasteur pipette was used to spread the paste over the surface and was then allowed to dry.

Product: Powder film on glass substrate
Description: PbI2, toluene, butyric acid, and butylamine were mixed in a capped flask. Separately, formamidinium acetate was dissolved in toluene and butyric acid. For this n=2 layered perovskite, the suspension was heated to 70 degrees Celsius and then cooled slowly, and the color changed from dark brown to red. The bright red is characteristic of this system. Centrifugation at 6000 rpm for three minutes was used to first isolate the solid, which was then re-dispersed in hexane and centrifuged again. This obtained the final paintlike paste solid.
