Shinji Kanegawa, Osamu Sato, Electronic Pyroelectricities in Heterometallic Dinucler Complexes, IRCCS The 3rd Joint International Symposium, 2020.01, Dinuclear valence tautomeric(VT) complexes [(M1(cth))(M2(cth)) (-dhbq)](PF6)3 [M1 = M2 = Co; 1[1], M1 = Cr, M2 = Co; 2[2], cth = hexamethyl tetraazacyclotetradecane, dhbq = dihydroxybenzoquinone] are very promising candidates for materials exhibiting electronic ferroelectricity and pyroelectricity. The VT complexes have stimuli-responsible intramolecular electron transfers, which result switching in electronic dipoles in a molecules. The pyroelectricities of a centrosymmetric crystal of 1 and a polar crystal of 2 were investigated by temperature sweep method. Both 1 and 2 exhibited VT behaviors with T1/2 = 245 K and 360 K, respectively, in magnetic measurements. However, only 2 showed thermally-induce electric current around VT transition temperature. The contrasting results between 1 and 2 obtained in pyroelectricities are well consistent with crystalline symmetries.. |
