  Two quinoxaline derivatives designed from isomer chemistry for nonvolatile ternary memory device applications

  摘要：

  In this paper, two quinoxaline-based small organic molecules, which are conjugated and mutual isomers in vertical and horizontal directions, were successfully synthesized. By exploring isomers with identical functional groups, the impact from changing in molecular composition on the observed different performance can be minimized. Their photoelectrical properties, thin-film morphology and the electrical memory performance were comparatively investigated. The devices based on these two small molecules both showed ternary WORM storage performance. Compared with vertical direction, horizontal molecule had a lower threshold voltage and higher current ratio. The results of AFM and XRD showed that horizontal molecule has better thin-film morphology and layered accumulation, which are conducive to the migration of carriers. We hope this study can provide a new reference to the future elaborate design and synthesis of novel small-molecule electrical memory materials. (C) 2015 Elsevier Ltd. All rights reserved.

  interlocked molecules to undergo this type of large-amplitude change is the core mechanism behind almost every interlocked molecular switch or machine, including sophisticated mechanical systems such as a molecular elevator and a peptide synthesizer. Here, as a way to expand the scope of dynamics possible at the molecular level, we have developed a molecular shuttling mechanism involving the exchange

  机械互锁的分子，例如轮烷和链烷烃包含两个或多个组分，其相对于彼此的运动可被控制。例如，[2]轮烷分子穿梭系统由一个带有两个识别位点的轴和一个可以沿着该轴往复运动（在识别位点之间穿梭）的单个大环轮组成。机械连锁分子经历这种大幅度变化的能力是几乎每个连锁分子开关或机器（包括复杂的机械系统，例如分子升降器和肽合成仪）背后的核心机制。在这里，作为扩大在分子水平上可能的动力学范围的一种方法，我们已经开发了一种分子穿梭机制，涉及在饱和[3]轮烷中的两个识别位点之间交换环（一个没有空的识别位点）。这是通过使较小的环穿过较大的环来完成的，从而实现环通环分子穿梭。
