Morphology-Driven Modulation of Charge Transport in Radical/Ion-Containing, Self-Assembled Block Copolymer Platform

A TEMPO‐substituted ionic liquid was selectively incorporated into well‐defined, self‐assembled block copolymer templates, which served as an active layer for organic nonvolatile memory. Phase structures (sphere, cylinder, and lamellae) and their orientation modulated the resistive switching behavio...

Description
Summary:A TEMPO‐substituted ionic liquid was selectively incorporated into well‐defined, self‐assembled block copolymer templates, which served as an active layer for organic nonvolatile memory. Phase structures (sphere, cylinder, and lamellae) and their orientation modulated the resistive switching behavior, which demonstrated the unprecedented, morphology‐driven charge transport in the organic electronic devices.
