Starting materials: PbCl2 (99.99%), Histamine (98%), HCl (36%), DMF
Product: Thin film on quartz substrate
Description: For preparing the crystals, equimolar amounts of PbCl2 (0.278g, 0.1 mmol) and histamine (0.113 g 0.1 mmol) were mixed in 10mL HCl 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 measure the UV-Vis absorption spectra.
