Abstract
Through precise and ingenious molecular modification, we successfully obtained a multiaxial ferroelectric, [FEtDabco]ZnI3 (N-fluoroethyl-N'-ZnI3-1,4-diazabicyclo[2.2.2]octonium), with a record high Tc (540 K) among molecular ferroelectrics, which is promising for application under extreme thermal conditions.
