Conductive Imide Films

9223390米勒最近的三个发展导致了这一提议。1.高各向异性导电性聚合物的电化学制备2.离子自由基在溶液中自组装成离域pi堆栈的第一个例子。3.芳香族(非脂肪族)自组装膜和Langmuir-Blodgett膜的形成。利用酰亚胺及其阴离子自由基构筑了三类特殊材料：聚酰亚胺堆积的导电聚合物薄膜、有序的芳香族表面层和具有导电表面的纳米树枝状大分子。用电化学、可见光谱、近红外光谱、红外光谱、XPS和ESR光谱、掠角红外光谱、可见光近红外线性二色性、X射线衍射、差示扫描量热法和电导率测量对这些材料进行了研究。这一结果有望在几个方面产生重大影响。这些新的材料类型几乎没有先例，而由圆周率堆积提供的分子间组织应该提供不同寻常的电学和光学性质。各向异性块体聚合物和纳米材料的合成有望从根本上揭示新的方法。***

9223390 Miller Three recent developments lead to this proposal. 1. The electrochemical preparation of a polymer with highly anisotropic conductivity. 2. The first example of self-assembly of ion- radicals into delocalized pi-stacks in solution. 3. The formation of aromatic (not aliphatic) self-assembled and Langmuir-Blodgett films. Using imides and their anion radicals, it is proposed to construct three types of unusual materials: conducting polymer films organized by pi-stacking; organized aromatic surface layers; and nanoscale dendrimers with conducting surfaces. These materials will be studied using electrochemistry, VIS, NIR, IR, XPS and ESR spectroscopy, grazing angle IR, VIS NIR linear dichroism, X-ray diffraction, DSC and conductivity measurements. The results promise to be significant in several regards. These new material types have little or no precedent, and the intermolecular organization provided by pi-stacking should provide unusual electrical and optical properties. It is expected that fundamentally new approaches to the synthesis of anisotropic bulk polymers and nanoscale materials will be revealed. ***
