项目摘要

This project has been planned to develop new design concepts on the novel organic responding molecules based on the integration of redox active molecules. The major themes to be tackled with are as follows : (1) Redox response systems with electrochemical bistability and surface modifying properties ; (2) New synthetic strategy for the fused- polyether structures ; (3) Redox active molecules with phase transition properties triggered by external stimuli.We have succeeded in preparing redox systems to meet the requirement in the first theme, and some of them are further endowed with multi-input and multi-output fuctionalities. The disuflide unit or ethynyl groups were selected that act as surface-binding linkers for Au an Si, respectively. Preparation of SAM and examination toward the realization of unimolecular memory are now under way.The fused-polyether skeleton found in some marine natural products should be a suitable motif for studying the aggregation by weak C-H--O hydrogen bonds … More . In the second theme, facile and general convergent strategy was developed for a variety of polyether skeleton. Based on the newly developed protocol based on the reaction between an aldehyde and an acylanion equivalent, we could synthesize polyetheral natural product (hemibrevetoxin B) and the large segments of ciguatoxins with 4-5 ether units. X-ray analyses on some of them have revealed that several short C-H--O contacts were observed that connect tape-shaped polyethers tol the stacked or dimeric strucures. Not only natural but also non-natural polyethers are shown worth investigated.Reversible oligomerization of bis(diarylethenyl)arenes-type electron donors upon oxidation is the outstanding achievement in terms of the third theme. Deeply-colored polycation oligomers could be isolated as stable salts that regenerated the starting monomeric donors upon reduction. By attaching long alkyl chains on the aryl groups, some of these materials act as organic gelators, thus giving a new desing concept for the dynamic mesophase, whose properties can be modulated by electrochemical input.

该项目已计划基于氧化还原活性分子的整合来开发有关新型有机负责分子的新设计概念。要解决的主要主题如下：（1）具有电化学双重性和表面修饰特性的氧化还原响应系统；（2）融合聚醚结构的新合成策略；（3）由外部刺激触发的具有相变特性的氧化还原活性分子。我们成功地准备了氧化还原系统以满足第一个主题中的需求，其中一些进一步赋予了多输入和多输血性能。选择了分别充当Au An Si的表面结合接头的拔出单位或乙醇基团。现在正在进行制备SAM和检查单分子记忆的检查。在某些海洋天然产物中发现的融合式晶体骨骼应该是研究通过弱的C-H-O氢键进行聚集的合适基序……更多。在第二个主题中，为各种多骨架制定了便捷和一般的收敛策略。基于新开发的方案，基于醛与酰基烷的反应之间的反应，我们可以合成多醚天然产物（半蛋白毒素B）和具有4-5醚单元的CIGUATOXIN的大段。对其中一些的X射线分析表明，观察到几个短的C-H-O触点连接胶带形的聚乙烯托管堆叠或二聚体结构。不仅自然而且还显示了非天然的聚乙烯。氧化后BIS（日二甲基苯基）领域型电子供体的可逆寡聚化是第三个主题的杰出成就。深色的聚乙烯可以分离为稳定的沙拉，在还原后再生单体供体。通过将长烷基链连接到芳基群上，其中一些材料充当有机凝胶剂，从而为动态中间机提供了一个新的降低概念，该材料可以通过电化学输入来调节其性质。较少的
