Donor–acceptor crosslinked nanoparticles with various donor/acceptor ratios and uniform sizes are synthesized successfully. The intramolecular charge transfer is effectively enhanced due to the incorporation of acceptor groups after the crosslinking reaction. A transistor memory device is assembled using the synthesized polymer and has nonvolatile flash‐type memory and amphiphilic trapping behavior. This study examines multiple applications of crosslinked core–shell nanoparticles, which demonstrates their promise as charge‐storage dielectric materials for use in organic memory devices.

Triazolium-based ion-conductive nanoparticles (NPs) with cross-linked cores were synthesized using a self-assembled block copolymer comprising site-selective cross-linking quaternization in a selective solvent. The NPs exhibited the ionic conductivities as high as 1.26 × 10−3 S/cm in the presence of 30 wt% ionic liquid at 90 °C, due to the enhanced segmental molecular motion and the formation of a preferable ionic-conductive path composed of the hydrophobic ionic-liquid based shell with the added ionic liquid.

Solution processable cross-linked core–shell poly(PEGMA)m-b-poly(DB3VT)n nanoparticles are firstly explored as charge storage materials for transistor-type memory devices owing to their efficient and controllable ability in electric charge transfer and trapping.
