Typical Ferroelectric Olefin-copper(I) Organometallic Oligmer with Flexible Organic Ligand

Solvothermal treatment of a flexible olefin organic ligand and CuBr offers a novel olefin-copper(I) coordination compound. The induction of the flexible ligand leads the olefin-copper(I) organometallic compound to crystallize in a chiral or polar point group P41. The investigation of its ferroelectric property shows that the compound is a typical ferroelectric and its electric hysteresis loop shows a remanent polarization (Pr) of ca. 0.2 μC/cm2 and coercive field (Ec) of 800 V/cm.
