AbstractOver the past few years, extremely high charge-storage capacities of glucose-based oligo- or polysaccharides have been discovered that enables such materials to hold a great potential in electronics applications due to their abundant and renewable materials. Typically, the introduction of an α-glucan-containing polysaccharide into the dielectric layer of a transistor-type memory device causes excellent irreversible electron-capture properties; hence, a transistor device embedded with oligosaccharide maltoheptaose domains expresses write-once-read-many (WORM)-type behavior, which confirms that green materials can be used for advanced electronics. However, their irreversible WORM-type characteristics also restrict the application α-glucan-containing polysaccharides in high-performance electronic devices. Recent advances in oligosaccharide-based block copolymers through the inherent immiscibility of different polymer segments can enhance not only the formation of self-assembled nanostructures but also the switching of memory properties. Furthermore, supramolecular structures composed of oligosaccharide-based block copolymers and conjugated moieties can be developed into high-performance nonvolatile organic field-effect transistor (OFET) memory devices. This mini review presents an overview of the recent literature in oligosaccharide maltoheptaose-based block copolymers and their promising applications in organic memory devices.Self-assemble introduction of α-glucan contained block copolymer materials into the particular layer of the memory devices have been impressed by their excellent performance. Some newly reported MH-based copolymer literatures in electronic application are discussed in this focus review, including the electron-trapping mechanism of oligosaccharide MH, the relationships between chemical structures and their supramolecules, self-assembly morphologies and the memory device characteristics of electronic devices. As a perspective, the glucose-based block copolymer materials have a great potential to develop into the greener generation for advanced green electronics.

自组装低聚糖基嵌段共聚物作为存储器件的电荷存储材料

摘要 在过去的几年中，人们发现了葡萄糖基寡糖或多糖具有极高的电荷存储能力，由于其丰富且可再生的材料，使得此类材料在电子应用中具有巨大的潜力。通常，将含 α-葡聚糖的多糖引入晶体管型存储器件的介电层会导致优异的不可逆电子捕获特性；因此，嵌入寡糖麦芽七糖结构域的晶体管器件表现出一次写入多次读取 (WORM) 类型的行为，这证实了绿色材料可用于先进电子产品。然而，它们不可逆的WORM型特性也限制了含α-葡聚糖的多糖在高性能电子设备中的应用。通过不同聚合物链段固有的不混溶性，基于寡糖的嵌段共聚物的最新进展不仅可以增强自组装纳米结构的形成，还可以增强记忆特性的转换。此外，由基于寡糖的嵌段共聚物和共轭部分组成的超分子结构可以开发成高性能的非易失性有机场效应晶体管 (OFET) 存储器件。这篇小型综述概述了基于低聚糖麦芽七糖的嵌段共聚物的最新文献及其在有机存储器件中的有前景的应用。 将含有 α-葡聚糖的嵌段共聚物材料自组装引入存储器件的特定层中他们的出色表现。本次重点综述讨论了一些新报道的电子应用中基于MH的共聚物文献，包括低聚糖MH的电子俘获机制、化学结构与其超分子之间的关系、自组装形态和电子器件的存储器件特性。从一个角度来看，基于葡萄糖的嵌段共聚物材料有很大的潜力发展成为先进绿色电子产品的绿色一代。
