제목 Molecular-Orientation-Driven Transient Behavior of Semicrystalline Polymeric Mixed Conductors
초록 Despite the importance of transient behavior in organic mixed ionicelectronic conductors, there are very few studies on material characteristics affecting ion drift and transient responses of corresponding organic electrochemical transistors (OECTs). In this work, we investigated the effect of molecular orientation of a polymeric mixed conductor system with glycol side chains on the transient behavior of OECTs by varying the co-monomer unit (2,2’-bithiophene or phenylene) used in conjunction with a novel 1,4-dithienylphenylene monomer. Two polymers with similar mixed conductivity and electrochemical characteristics except molecular orientation were successfully synthesized. The comprehensive analysis of the OECT characteristics showed that the molecular orientation affects the length of the ion-drift pathway correlated with ion mobility, resulting in different transient behavior in OECT devices.
