1. A Highly Ordered Structure in N-Octadecylacrylamide Langmuir-Blodgett MultilayrsFT-IR spectroscopic measurements of N-octadecylacrylamide (ODA) LB films indicate that ODA are oriented nearly perpendicular to the surface plate ; moreover they are ordered in the plane along the dipping direction (in-plane order). A drastic dichroism in polarized FT-IR caused by the large anisotropic arrangement of ODA molecules was observed.2. Phase Transition Behavior of Monolayrs of Acrylamides with Double Alkyl ChainsThe monolayrs of N,N-dialkylacrylamide (dAA) monomers can be classified into three types, (I) a rigid condensed monolayr, (II) a phase transition monolayr, and (III) a expanded monolayr. The similar three kinds of monolayrs are observed in the isotherms for dHDA monolayr as a function of temperature. Two carbon elongation in double alkyl chains causes the same effect on the monolayr induced by about 10ﾟC cooling.3. Electrochemical Response of Hetero-Deposited Redox polymer LB FilmsThe … More hetero-deposited LB film with three ruthenium complex (Ru) monolayrs and two ferrocene derivatives (Fc) monolayrs are deposited onto ITO electrode. The outer LB film sites remain trapped in the oxidized Fc state, which is regraded as a charge strage. They demonstrate that the unidirectional electrton trasnfer across the interface between Ru and Fc LB films is realized by the hetero-deposited redox polymer LB films4. Photocurrent Response of Polymer LB Film with Tris (bipyridine) ruthenium DerivativeOn light irradiation onto the N-tert-Pentylacrylamide (tPA) copolymer containing Ru(bpy)_3^<2+>p(tPA-Ru) monolayr deposited ITO electrode, a photocurrent generation was observed in the presence of thiosalicylic acid as a sacrificial electron donor. As the mechanism for phtocurrent generation, we consider that Ru(bpy)_3^<2+> is first excited by light irradiation and the excited state is efficiently quenched by thiolate anion forming Ru^+ species. Finally, an anodic current is produced by electron transfer reaction from Ru^+ to ITO electrode.5. Drawing Fine Patterns with Cross-Linkable Polymer LB FilmLB films of copolymer consisting of N-dodecylacrylamide (DDA), and cross-linkable group, N-omega-acryloylundecyl-4-vinylpyridinium salt were prepared. On UV irradiation, the cross-linking reaction occurs efficiently giving uniform two-dimentional cross-linked polymer LB films with a high stability against solvents. The photolithographic property of the LB film are applicalbe to a new tyoe of high resolution negative photoresists. Less

1.N-十八烷基丙烯酰胺Langmuir-Blodgett多层膜中高度有序结构的FT-IR光谱测试表明，oda几乎垂直于表面板取向，且沿浸渍方向在平面内有序排列。实验结果表明：1.在偏振红外光谱中，由于oda分子的大的各向异性排列，导致了强烈的二色性。N，N-二烷基丙烯酰胺(DAA)单体的单层相变行为N，N-二烷基丙烯酰胺(DAA)单体可分为三种类型：(1)刚性凝聚单层；(2)相变单层；(3)膨胀单层。在dHDA单分子层的等温线中观察到类似的三种单分子层随温度的变化。双烷基链上的两个碳伸长对约10ﾟC冷却诱导的单分子层有相同的影响。…异质沉积氧化还原聚合物LB膜的电化学响应在ITO电极上沉积了更多具有3个Ru单层和2个二茂铁衍生物(FC)单层的LB膜。外层的LB膜位置仍然处于氧化的Fc态，这被归类为电荷带。它们证明了Ru和Fc LB膜之间的单向电子转移是通过异相沉积的氧化还原聚合物LB膜实现的。含三(联吡啶)Ru衍生物的聚合物LB膜的光电流响应在含有Ru(Bpy)_3^&lt；2+&gt；p(tPA-Ru)单层沉积电极的N-叔丁基丙烯酰胺(TPA)共聚物(TPA)上，在硫代水杨酸作为牺牲电子供体的存在下，观察到光电流的产生。作为光电流产生的机制，我们认为Ru(Bpy)_3^&lt；2+&gt；首先被光激发，激发态被形成Ru~(++)物种的硫酸盐阴离子有效地猝灭。最后，通过Ru~(2+)向ITO电极的电子转移反应产生阳极电流。由N-十二烷基丙烯酰胺(DDA)和可交联基N-丙烯酰基-4-乙烯基吡啶盐组成的共聚物的LB膜的制备。在紫外光照射下，有效地进行了交联反应，得到了均匀的二维交联聚合物LB膜，对溶剂具有很高的稳定性。LB膜的光刻性能适用于一种新型的高分辨率负性光刻胶。较少
