Pressure response effect on chiral 2D perovskites

The goal of this proposal is to characterize the structural evolution as a function of pressure at room temperature of a prototype 2D chiral perovskite, namely ClMBA2PbI4 (ClMBA= chloro-methylbenzylammonium) in the two enantiopure samples (R and S) and in the racemate. The structural study will be coupled to the spectroscopic measurements as a function of pressure, in particular circular photoluminescence (CPL), to fully characterize the behaviour of these low dimensional hybrid perovskites upon compression and unveil the evolution of non-linear optical properties and chirality transfer induced by the chiral cation.
