Synthesis, characterization and phase transitions of the inorganic–organic layered perovskite-type hybrids [(CnH2n+1NH3)2PbI4] (n = 12, 14, 16 and 18)

Abstract

The room temperature single-crystal structures of the inorganic–organic layered perovskite-type hybrids of general formula [(CnH2n+1NH3)2PbI4] (n = 12, 14, 16 and 18) have been determined. The four compounds each display two reversible phase transitions above room temperature, with phases labelled III, II and I. The single-crystal structures of phase II have also been determined. The phase transition from phase III to phase II is a first-order transition and corresponds to a change in the conformation of the alkylammonium chains and a shift of the inorganic layers relative to each other. The phase change from III to II is thermochromic for all compounds, going from a yellow to an orange colour.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
