2D Chiral Uranyl(VI) Coordination Polymers with Second‐Harmonic Generation Response and Ferroelectric Properties

Abstract

The in situ hydrothermal reactions of UO 2 (NO 3 ) 2 with 1-oxo-4-cyanopyridine (ocpy) and ethyl (S)-lactate (e-la) afforded two unprecedented chiral 2D neutral luminescent square grids, uranyl-bis(1-oxo-4-pyridylcarboxylate) UO 2 (opyca) 2 (1) and homochiral uranyl-bis[(S)-lactate] (2). Their solid-

Synthesis, structure characterization and photocatalytic properties of two new uranyl naphthalene-dicarboxylate coordination polymer compounds

“…4). Five characteristic emission peaks are observed in the range of 480-570 nm for UO 2 (Ac) 2 upon excitation at 341 nm, in agreement with the results observed previously [9]. Compounds 1 and 2 show strong emissions at 362 and 390 nm, respectively, when excited at 341 nm.…”

Soluble dynamic coordination polymers as a paradigm for materials science

“…These polymers are now intensely studied due to their unusual properties provided by the metal ion, e.g. molecular-magnetism [8][9][10][11][12][13], synthetic metallic conduction [14][15][16][17], non-linear optics [18][19][20][21] and ferroelectrics [22][23][24][25], and this, in combination with the outstanding mechanical properties of conventional polymers. The possibility to modify their magnetic, electric and optical properties as well as their morphology by the choice of the involved metal ions and the manipulation of its redox properties in addition to the ligands opens pathways to a completely new class of functional materials.…”

Crystal Structure and Phase Transition of the C–H···F–H-Bonded Supramolecular Compound with 4-Nitroanilinium Based on 18-Crown-6

“…Research on solid-state materials is increasingly attracting interest owing to their potential versatile technical applications, such as molecular sensors, switches, and data-storage devices [1][2][3][4]. Among them, phase-transition crystalline materials are important and often cause significant changes in physical and chemical properties.…”
