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

摘要

The in situ hydrothermal reactions of UO_2(NO_2)_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 state structures,preliminary optical and photolumnesent properties are reported.
