An Electrochemical Approach to Synthesis & Characterization of Novel Coordination Polymers: The Generation of Materials Having Unusual Structural and Charge Transfer Properties

该奖项是在先进材料和加工项目中颁发的，以支持安德鲁·博卡斯利教授的研究。化学司提供支助。研究的主要内容是氰金属酸盐配位聚合物的合成、电化学、流变学和形态表征。将研究三个具体领域：(1)由氰化铁-铂（IV）四胺电化学氧化形成的氰桥接聚合物的合成。(2)四氯化钯与亚铁氰化物或铁氰化物配位聚合物的合成。这些聚合物是水凝胶，其流变性和形态学性质将被研究。(3)将氰化物桥接的Fe-Pt聚合物层置于镍电极上，形成光化学图案。这种化学反应将导致瞬态光学光栅，它将被用来探测从电极表面穿过聚合物层的横向和垂直电荷转移的细节。这样的系统可以提供新的电光开关。氰金属酸盐配位聚合物是一种相对未开发的材料，其氧化还原、光学和流变性能可能导致一系列新的电子、光学和结构应用。* * *

9312056 Bocarsly This award is made in the Advanced Materials and Processing Program in support of the research of Professor Andrew Bocarsley. Support is provided by the Chemistry Division. The general thrust of the research is the synthesis, electrochemistry and rheological and morphological characterization of cyanometallate coordination polymers. Three specific areas will be investigated: (1) Synthesis of cyano-bridged polymers formed by electrochemical oxidation of a ferrocyanide-Pt(IV) tetrammine. (2) Synthesis of coordination polymers based on Pd(II) tetrachloride and either ferrocyanide or ferricyanide. These polymers are hydrogels whose rheological and morphological properties will be studied. (3) Layers of the cyanide bridged Fe-Pt polymer, placed on a nickel electrode will be photochemically patterned. This chemistry will lead to transient optical gratings which will be employed to probe the details of lateral and perpendicular charge-transfer from the electrode surface through the polymer layer. Such systems may provide for novel electro-optical switches. %%% Cyanometallate coordination polymers are relatively unexplored materials whose redox, optical and rheological properties may lead to a host of novel electronic, optical and structural applications. ***
