An organic–inorganic hybrid perovskite containing copper paddle-wheel clusters linking perovskite layers : [Cu(O2C–(CH2)3–NH3)2]PbBr4†
Abstract
The incorporation of Cu2(CO2)4 clusters, built up from amino carboxylic acid zwitterionic molecules, led both to the stabilization of a layered hybrid perovskite, and to the formation of a covalent bond pathway between adjacent perovskite layers.
