A layered hybrid perovskite belonging to the <110> series, (FA) 2 (HEA) 2 Pb 2 Br 8 (HEA + , hydroxyethylammonium; FA + , formamidinium) exhibits a bright green narrow emission and a reversible mechanochromic luminescence effect: after grinding the powder a few seconds, the emission is blue shifted from 500 to 480 nm due to a partial amorphization. PeLEDs based on (FA) 2 (HEA) 2 Pb 2 Br 8 as active material were also demonstrated, which is unprecedented for such a layered hybrid perovskite.
