Ethylamine Hydroiodide Usage And Synthesis
Applications Ethylammonium iodide (EAI), like methylammonium iodide, is a precursor used for high-efficiency pervoskite solar cells and LEDs.
(CH3CH2NH3)PbI3 has valence band position at 5.6 eV with an optical band-gap of ca.2.2 eV [2]. In comparison, (CH3NH3)PbI3 has a valence band position at 5.4 eV with an optical band-gap of 1.5 eV. The difference is due to the larger cation effect of (CH3CH2NH3)PbI3, resulting in less conjugation to the lead iodide to widen the band-gap of the perovskite structure.
Our company was built in 2009 with an ISO certificate.In the past 6 years, we have grown up as a famous fine chemicals supplier in China and we had established stable business relationships with Samsung,LG,Merck,Thermo Fisher Scientific and so on.Our main business covers the fields below:
1.Noble Metal Catalysts (Pt.Pd...)
2.Organic Phosphine Ligands (Tert-butyl-phosphine.Cyclohexyl-phosphine...)
3.OLED intermediates (Fluorene,Carbazole,Boric acid...)
4.Customs Synthesis
Our advantage:
