Efficient in-Plane Exciton Transport in a Discontinuous Layered Lead-Bromide Perovskite.
This study reports a new class of two-dimensional lead-bromide perovskite based on monovalent 4-aminomethylbenzoic acid (AMBA) cations featuring a discontinuous inorganic layer. Strong hydrogen-bonding interactions at the interlayer between AMBA molecules impose structural rigidity that prevents the formation of contin...
