Starting materials: Histamine, PbBr2, HBr
Product: plate-like yellow crystals
Description: 0.34 mmol PbBr2, 0.35 mmol histamine are mixed in 3 mL of 9M HBr. The mixture is then heated to 100 ˚C for 2 h to dissolve the solid, and then slowly cooled down to room temperature at −2 °C·hr−1.
Method: Single crystal X-ray diffraction
Description: Frames were collected using Bruker D8 Venture diffractometer equipped with a Photon 100 CMOS detector employing Mo Kα radiation (λ=0.71073 Å).
Starting materials: PbBr2 (99.99%), Histamine (98%), HBr (40%), DMF
Product: Thin film on quartz substrate
Description: For preparing the crystals, equimolar amounts of PbBr2 (0.367g, 0.1 mmol) and histamine (0.113 g 0.1 mmol) were mixed in 10mL HBr by heating and refluxing at 90 °C and then, the solution slowly cooled to room temperature in N2 atmosphere. 10 mg of the obtained single crystals were dissolved into 1.5 mL dried DMF solution and then the solution was coated onto a quartz substrate. The spin cycle spent 1 s accelerating to 1200 rmp and then stayed at that rotation speed for 50 s. The substrate was then heated to 100 °C for 20 minutes.
Method: UV-Vis absorption
Description: A Hitachi F-4100 spectrofluorimeter was used to record the UV-Vis absorption spectra.

Method: Photoluminescence Spectroscopy
Description: A Hitachi F-4500 spectrofluorimeter was used for emission spectra. A 150 W xenon lamp was used as the excitation source.
