Structural diversity in proline-based lead bromide chiral perovskites

“…Previously, the chirality of l -/ d -proline has been exploited to obtain chiral non-centrosymmetric compounds that exhibit nonlinear optical properties. 39–46 Taking into account that proline exists in its cationic form at low pH, thus containing a positively charged –NH 2 + – group which can interact with the negatively charged anionic inorganic framework both ionically and through hydrogen bonding, this amino acid can be effectively used to produce novel and highly demanded chiral HOIPs.…”

“…Previously, the chirality of L-/D-proline has been exploited to obtain chiral non-centrosymmetric compounds that exhibit nonlinear optical properties. [39][40][41][42][43][44][45][46] Taking into account that proline exists in its cationic form at low pH, thus containing a positively charged -NH 2 +group which can interact with the negatively charged anionic inorganic framework both ionically and through hydrogen bonding, this amino acid can be effectively used to produce novel and highly demanded chiral HOIPs. Herein, we prepared two new low-dimensional homochiral lead-halide HOIPs by using α-amino acid L-proline, namely (L-proH)PbBr According to single-crystal XRD, the structural motifs of the inorganic sub-lattice of compound Pro-PbBr 3 are established by infinite 1D chains consisting of face-shared lead halide octahedra, whereas the inorganic sub-lattice of compound Pro-Pb 3 Br 10 is less common and established by 2D honeycombtype inorganic layers simultaneously containing corner-and face-shared lead bromide octahedra.…”
