“…7 Atom Pb(1) has a more regular coordination geometry, as it lies on an inversion centre, which ensures that all trans angles are exactly 180 . The angles between cis iodides are in the range 84.182 (19) to 95.818 (19) . The bond distances are in a narrow range from 3.2150 (9) A to 3.2260(10) A.…”

“…Meanwhile, significant differences in the bond length of Cd–Cl and the distance between octahedrons were found among the three crystals (Table S3 and Figures S2d–f and S3). In the stacking structure of organic cations, adjacent aromatic rings are arranged vertically in p PC . However, the distances between adjacent aromatic rings in o PC and m PC are 3.187 and 3.368 Å, respectively, indicating the existence of π–π stacking interactions in the two crystals (Figure S3d–f).…”

Low-dimensional organic−inorganic hybrid perovskites (OIHPs) have shown significant potential in the optoelectronic field due to their adjustable structure and properties. However, the poor air stability and flexibility of the OIHP crystals limit their further development. Herein, three OIHP crystals have been synthesized using cadmium chloride and the isomer of phenylenediamine as raw materials. Mn 2+ doping turns on the red-light emission of Cd-based OIHPs at around 625 nm. Interestingly, the organic ligands with different steric hindrance can induce a transition of the OIHP structure from two dimensions (2D) to one dimension (1D), thereby regulating the quantum yield of red luminescence in the range of 38.4% to nearly 100%. It is found that the surface-exposed amino groups are easy to oxidize, resulting in the instability of these OIHP crystals. Therefore, poly(lactic acid) (PLA) is selected to passivate OIHPs through hydrogen bonding between C�O of PLA and −NH 2 on the surface of OIHPs. As a result, the production of OIHP-based flexible films with highly efficient and stable red emission can be obtained after being encapsulated by PLA. They demonstrate enormous application potential in flexible X-ray imaging. This study not only realizes stable perovskite films but also provides an effective design idea for red flexible scintillators.
