Here we study the Jahn-Teller (JT) effect on framework flexibility of two analogous hybrid organic-inorganic perovskites, [C(NH2)3][Zn(HCOO)3] (1-Zn) and [C(NH2)3][Cu(HCOO)3] (2-Cu). Single-crystal nanoindentation measurements show that elastic moduli hardnesses 1-Zn are up to ∼52.0% ∼25.0% greater than those JT active 2-Cu. Temperature-dependent X-ray diffraction indicate thermal expansion along b-axis is switched from negative positive by replacing Zn2+ with Cu2+ B-site. These stark...
The isolation of 2D materials from mother bulks into nanoscale is vital importance for fulfilling their applications in many technological fields. Among known methods, mechanical exfoliation one the most widely utilized ways due to its simplicity. For a given material, both interlayer and intralayer bonding strengths need be taken account understanding process as former dominates ease level cleaving adjacent molecular layers while latter regulates ability resist cracking. In this regard,...
High pressure behavior of a 2D hybrid perovskite semiconductor, (BA)2PbBr4 (BA = benzylammonium), has been systematically studied via synchrotron powder X-ray diffraction over the range 0-14.22 GPa. shows soft nature with bulk modulus 10(1) GPa and anisotropic linear compressibility βa 25(6), βb 5.3(4), βc 15.1(8) TPa−1. Experiment-aided density functional theory calculations reveal that structural changes under compression are attributed to configurational alterations BA+ organic cations...
Very few materials expand two-dimensionally under pressure, and this extremely rare phenomenon, namely negative area compressibility (NAC), is highly desirable for technological applications in pressure sensors actuators. Hitherto, the known NAC have dominantly been limited to 2D crystals bonded via coordination interactions while other systems not explored yet. Here, we report large of a hydrogen-bonded supramolecular complex, Zn(CH3COO)2·2H2O, with synergistic microscopic mechanism. Our...
Two-dimensional (2D) hybrid organic–inorganic perovskites (HOIPs) have garnered plentiful attention as a result of their exceptional structural flexibility and multiple applications. In this study, we present 2D HOIP (CHA)2PbBr4 (CHA = cyclohexylamine), for its potential applications in piezoelectricity, such strain energy sensing harvesting. Flexible composite films (CHA)2PbBr4/PDMS (PDMS polydimethylsiloxane) with sequence weight ratios (0, 5, 10, 15, 20 wt %) were fabricated to analyze...
