KGaA, Weinheim Donor–acceptor crosslinked poly[poly(ethylene glycol) methyl ether-methacrylate]-block-poly[1,1′-bis(2-ethylpentyl)-6-methyl-6′-(5-methyl-3-vinylthiophen-2-yl)-[3,3′-biindoline]-2,2′-dione] (poly(PEGMA)m-b-poly(VTIID)n) nanoparticles with various vinylthiophene donor/isoindigo acceptor ratios are synthesized successfully. The prepared nanoparticles have uniform sizes and well-defined core–shell nanostructures. 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. The optimized devices exhibit a significant memory window of approximately 38 V, a retention ability of over 104 s, and an endurance of at least 100 cycles. 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. |
