4-Trifluoromethyl-Phenylammonium bromide

• 
  Borun New Material - ChemBorun offers the greatest range of alkylammonium bromides enabling researchers to investigate the effect of cation sizes in perovskite structures and to customise opto-electronic devices to various specifications. The cation 4-trifluoromethyl-phenylammonium displays a higher binding to acceptor-type defects on perovskite grain surfaces compared to phenethylammonium thanks to the highly electronegative fluorine atoms (Lin et al., 2022).
  
  Borun New Material - ChemBorun's 4-trifluoromethyl-phenylammonium bromide (CF3-PABr; CAS Number: 148819-81-2) is of the highest purity affording consistent results and superior performance.
