Anomalous dielectric behaviour in centrosymmetric organic–inorganic hybrid chlorobismuthate(III) containing functional N,N-dimethylethylammonium ligand. Crystal structure and properties

Tunable Dielectric Responses Triggered by Dimensionality Modification in Organic–Inorganic Hybrid Phase Transition Compounds (C5H6N)CdnCl2n+1 (n = 1 and 2)

“…E a and τ 0 can be approximately calculated to be 0.275 eV and 1.19 × 10 –14 s, respectively, using a ln τ versus 1/ T plot of the polycrystalline sample (Figure S11, Supporting Information). Such dielectric relaxation behavior can also be observed in some other phase transition compounds. ,,− Accordingly, the dielectric relaxation behavior of 2 may be explained by the swing and the reorientational motions of the Py cations. During the cooling process, the frozen orientational motions of Py cations are unable to make enough responses to the change in the external electric field with deceasing temperature.…”

Temperature-Triggered Dielectric-Optical Duple Switch Based on an Organic–Inorganic Hybrid Phase Transition Crystal: [C5N2H16]2SbBr5

“…For instance, Tarasiewicz et al and Jakubas and Sobczyk reported the crystal structures of [ n -C 4 H 9 NH 3 ] 2 [SbBr 5 ] and [ n -C 5 H 11 NH 3 ] 2 [SbBr 5 ], which exhibit interesting phase transition properties. The imidazolium analogues have also been reported with order–disorder phase transition characters. , However, most investigations in this group have focused on simple monoamines or their derivatives, whereas in comparison, diammonium derivatives have received much less attention. − …”

Zn2+ and Cu2+ doping of one-dimensional lead-free hybrid perovskite ABX3 for white light emission and green solar cell applications

“…Nowadays, hybrid molecular crystals based on metal halides have received increasing attention for their interesting biological, opto-electronic, luminescence and magnetic properties. [1][2][3][4][5][6][7][8][9][10] Organic-inorganic metal halide-based perovskites (OIMHP) are acclaimed for their electrical and opto-electrical properties. [11][12][13][14][15][16][17][18][19][20] In fact, because of their low band gap energies around 1.5 eV, the three dimensional (3-D) OIMHP are widely used in photovoltaic solar cells (SCs).…”
