Starting materials: 2T•HI(2T: bithiophenylethylammonium), tin iodide (SnI2), dimethylformide (DMF), anhydrous chlorobenzene (CB), SiO2 (300 nm)/Si substrates
Product: <5 layers thick crystal
Description: The process was carried out inside an N2-filled glovebox. 10 μmol of SnI2 and 20 μmol of 2T.HI were dissolved in 2 ml of DMF/CB co-solvent (1:1 v/v). The stock solution was then diluted 120 times by CB/AN/DCB co-solvent (2.5:1:0.01 volume ratio). 5–10 μl of the diluted solution was added onto the pre-cleaned substrate. CB vapor was allowed to be diffused at 70 °C for 10-30 min.
Method: Photoluminescence
Description: The PL spectrum was recorded using the SpectraPro HRS-300 spectrometer.

Starting materials: 2T•HI(2T: bithiophenylethylammonium), lead iodide (PbI2), dimethylformide (DMF), anhydrous chlorobenzene (CB)
Product: sheet-like crystals
Description: 10 μmol of PbI2 and 20 μmol of 2T•HI were dissolved in 2 mL of DMF/CB co-solvent (1:1 ration). This resulted in 5 mM of stock solution. This solution was diluted 120 times by CB/An/DCB cosolvent (9.5:1:0.01 volume ratio). Only 5-10 μmol was placed on a growth substrate SiO2, at the bottom of a glass vial and was later transferred to another vial with 3 mL of CB. This was placed on a 70º hot plate. Growth took 10-30 minutes.
Method: Single Crystal X-Ray Diffraction
Description: Bruker AXS D8 Quest CMOS diffractometer with kappa geometry, an I-μ-S microsource X-ray tube, multilayer Göbel mirror, and Photon2 CMOS was used. Data was collected with Cu Kα radiation (λ = 1.54178 Å).
