Ferroelectric metal-organic coordination polymer with a high dielectric constant

摘要

Two homochiral MOFs, (CBQ)Cu-3(I)(CN)(3)Br (1) and (CBC) Cu-2.5(I)(CN)(2)Br-1.5 (2), were prepared by the solvothermal reaction of CuCN with N-4-cyanobenzyl quinidinium bromide (CBQ-Br) and N-4-cyanobenzylcinchonidinium bromide (CBC-Br). 1 and 2 are typical ferroelectric compounds while 1 may have dipolar relaxation ferroelectrics and a high dielectric constant (epsilon(o) = 119.3).
