Mechanically rigid 2D lead halide perovskite (PMA) <sub>2</sub> PbCl <sub>4</sub> with pressure-stable broadband emission
(PMA) 2 PbCl 4 , undergoes anisotropic lattice contraction, octahedral distortions, and organic–inorganic coupling, driving a crossover from free-exciton to pressure-stable broadband emission due to self-trapped excitons.
