The homogenous, [IrCp∗I2]2, SCRAM catalyst (1) is active in the racemization of chiral amines. NMR, kinetic and structural mechanistic studies have determined cause deactivation to occur when ammonia or methylamine are liberated by hydrolysis aminolysis intermediate imine, which tightly coordinate iridium centre block turnover. Control moisture substrate concentration can suppress deactivation,...

Methylamine molecular treatment (MMT) either in precursor ink or final film of perovskite has been widely proposed to trigger high-efficiency, room-temperature, green-solvent, fast crystallization, and high-throughput processing solar cells but exclusively limited methylammonium (MA)-based perovskites, which is due the reversible exchange between external methylamine (MA0) molecule same molecul...
