Research Abstract |
Dielectric properties based on flip-flop motion of dipoles upon molecular rotation were investigated by changing arylammonium and crown ether derivatives. Adamantane derivative with pseudo C3 symmetry was also studied. Although pyridazinium has no NH3 substituent worked as rotational axis, the molecule can be fixed by weak hydrogen bonds in the crystalline voids. The molecular motion upon applying external field was resulted in a large dielectric response. It was also attempted to introduce two proton accepting sites in the rotator to evaluate the possibility of hybrid dielectric response by proton transfer and molecular rotation.
