Abstract

Colorless crystals of (CH₃NH₃·H₂O)PbI₃ spontaneously lose water at 298 K which triggers a transformation to the black (CH₃NH₃)PbI₃ perovskite in the solid state as a porous microcrystalline solid with nanoscale substructure, but the dihydrate (CH₃NH₃)₄PbI₆·2H₂O) requires much more forcing conditions to produce (CH₃NH₃)PbI₃.
