Journal ArticleDOI
Planarized Star-Shaped Oligothiophenes with Enhanced π-Electron Delocalization
TL;DR: Results associated with theoretical calculations show the advantage of benzotrithiophene as a central core in terms of pi-electron delocalization and cyclic voltammetry and UV-visible spectroscopy.
Journal ArticleDOI
Effect of mono- versus di-ammonium cation of 2,2'-bithiophene derivatives on the structure of organic-inorganic hybrid materials based on iodo metallates
Xu-Hui Zhu,Nicolas Mercier,Pierre Frère,Philippe Blanchard,Jean Roncali,Magali Allain,Claude Pasquier,Amédée Riou +7 more
TL;DR: Three layered compounds designed for their incorporation in organic-inorganic materials based on iodometalates have been synthesized as crystals from slowly cooled aqueous solution containing metal halide and bithiophene derivative salts, revealing a semiconductive behavior and molecular interactions.
Journal ArticleDOI
Thermally Induced Bi(III) Lone Pair Stereoactivity: Ferroelectric Phase Transition and Semiconducting Properties of (MV)BiBr5 (MV= methylviologen)
TL;DR: In this paper, the BiBr5 chains of trans-connected octahedra are stabilized by methyviologen cations, and the Bi3+ electron lone pair is sterochemically activated below −30 °C, leading to an acentric polar phase.
Journal ArticleDOI
Large spontaneous polarization and clear hysteresis loop of a room-temperature hybrid ferroelectric based on mixed-halide [BiI3Cl2] polar chains and methylviologen dication.
Nicolas Leblanc,Nicolas Mercier,Leokadiya V. Zorina,Sergey V. Simonov,Pascale Auban-Senzier,Claude Pasquier +5 more
TL;DR: Of great importance is that this room-temperature hybrid ferroelectric displays a clear electrical hysteresis loop with a large spontaneous polarization (>15 μC·cm(-2)).
Journal ArticleDOI
Unique hydrogen bonding correlating with a reduced band gap and phase transition in the hybrid perovskites (HO(CH2)2NH3)2PbX4 (X = I, Br).
TL;DR: A change in the hydrogen bonding occurs, with molecules standing up in the interlayer space and OH parts probably interacting together, leading to a more conventional situation for ammonium groups and a more distorted perovskite layer.
