Abstract
Highly phase-pure, two-dimensional, multilayered organic-inorganic hybrid, halide perovskites are provided. Also provided are optoelectronic devices that incorporate the halide perovskites as photoactive materials.
Claims22
A material comprising homologous, two-dimensional halide perovskites having the formula (RNH3)2A(n−1)MnX(3n+1) or the formula (H3NRNH3)A(n−1)MnX(3n+1), where R is an aliphatic or aromatic chain, A is a small organic or inorganic cation, M is a divalent metal cation, X is a halide anion, and n is an integer having a value of 3 or greater, wherein at least 95%, based on mole fraction, of the material comprises the two-dimensional halide perovskites having the same n value.
A material comprising homologous, two-dimensional halide perovskites having the formula (RNH3)AnMnX(3n+1), where R is an aliphatic or aromatic chain, A is a small organic or inorganic cation, M is a divalent metal cation, X is a halide anion, and n is an integer having a value of 1 or greater.
