| Research Abstract |
A well-defined mesostructure of block copolymer templates was successfully functionalized with redox-active radicals and charge-compensating ionic groups via ionic liquid-assisted self-assembly. The obtained PS-b-PEO layer containing TEMPO-IL 1 exhibited morphology-driven modulation of charge-transport (on/off switching) in an organic thin film device. Location of radical and ionic molecules was correlated with resistive memory characteristics (rewritable/WORM, etc). We applied Kelvin Probe Force Microscopy (KPFM) technique and conductive AFM to visualize local surface potential and local conductivity change of microdomains under the programmed bias. Radical- and ion-functionalized block copolymers were also synthesized via controlled radical polymerization and ring-opening metathesis polymerization, and utilized as the active layer for organic memory.
