Deuteration Effect of Ferroelectricity and Permittivity on Homochiral Zinc Coordination Compound
2007-09-05T00:00:00Z (GMT) by
Hydrothermal [2+3] cycloaddition reactions of N-4‘-caynobenzylcinchonidine bromide (CBCBr) with NaN3 in the presence of ZnBr2 offer a novel Zn dimer (CBC−N4)2ZnBr2(N3)2(X2O), X = H for 1 and D for 2) in which the reactant Br- and N3- take part in the coordination to Zn. The measurements of ferroelectricity and permittivity of 1 and 2 show that there exists a large deuterated effect both in ferroelectric behavior (40% increase) and in dielectric constant (2.75 times increase), which is unprecedented in metal coordination compounds.
