Abstract
We report a one-step, solvent-free, green approach for the mechanochemical stabilization of hybrid organic–inorganic lead halide (MAPbBr3) perovskite quantum dots (PQDs) within perovskite metal–organic frameworks (MOFs) [MA-M(HCOO)3] [M = Mn and Co; MA = methylammonium (CH3NH3+)]. The perovskite MOF acts as a template and source of MA cations for growing and stabilizing hybrid PQDs. The synthesis of the composite has been carried out mechanochemically, without the use of any external reagents by simply grinding the perovskite MOF with PbBr2. MAPbBr3@MA-Mn(HCOO)3 composite shows high chemical stability in several solvents. Its excellent processability has been demonstrated by using it as an electrode material which shows photoelectrochemical activity in the presence of light.
