项目摘要

A DNA/polyaniline(PAn) highly ordered hybrid has been successfully prepared by the photopolymeization of dimeric aniline via photocatalytic reaction with Ru(bpy)_3^<2+> complex in the presence of DNA template, a reaction which occurs, even in the solution at pH 3.0-6.0,due to the specific local "lower-pH" environment provided by DNA. In this hybrid, the PAn was associated with DNA, and the chain structure of the PAn was revealed to be affected by the helical structure of the DNA. The resulting DNA/PAn complex contained Ru(bpy)_3^<2+> photocatalyst its structure even after purification. The complex was revealed to work as a material for novel organic red-emitting diode.One of shortcomings of this photopolymerized DNA/PAn hybrid is the low molar mass of the obtained PAn. In order to increase the molar mass and to improve the electronic properties of the resulting DNA/PAn hybrid, we first prepared DNA/PAn hybrid with chemically polymerized PAn with higher molar mass. The preparation procedure is very simple, just mixing the DNA solution with the chemically polymerized PAn solution. We successfully found out the adequate mixing condition to prepare the DNA/PAn hybrid with highly ordered structure similar to the photopolymerized one.We have already reported an EL device composed of DNA/PAn hybrid and analyzed the charge transport mechanism of the hybrid. From these results, it was clear that charge carriers migrated along DNA/PAn chain and that the hybrid was expected to be molecular wire. In this research, as the second purpose, we studied molecular alignment of DNA hybrid by means of ac field. Finally, we successfully demonstrated the molecular alignment of the DNA/PAn hybrid between electrodes to study the electronic properties as molecular wire.

DNA/聚苯胺（PAN）高度有序的杂化已通过与RU（BPY）_3^<2+>复合物的光催化反应的光聚糖化来制备，在存在DNA模板的情况下，即使在pH 3.0-6.0的溶液中也会发生在pH 3.0-6.0的情况下，由于特定的局部局部“下ph 3.0-6.0）也会发生。在这种杂种中，锅与DNA相关，锅的链结构显示出受DNA的螺旋结构的影响。所得的DNA/PAN复合物包含RU（BPY）_3^<2+>光催化剂的结构，即使在纯化后也是如此。该复合物被揭示为新颖的有机红发射二极管的材料。这种光聚合DNA/PAN杂种的缺点是所获得的PAN的低摩尔质量。为了增加摩尔质量并改善所得DNA/PAN杂种的电子性能，我们首先使用具有较高摩尔质量的化学聚合PAN制备了DNA/PAN杂种。制备过程非常简单，只需将DNA溶液与化学聚合锅溶液混合。我们成功地发现了足够的混合条件，以制备具有类似于光聚合剂的高度有序结构的DNA/PAN混合体。我们已经报道了由DNA/PAN混合动力组成的EL设备，并分析了混合动力的电荷传输机制。从这些结果可以明显看出，沿DNA/PAN链迁移的电荷载体预计将是分子线。在这项研究中，作为第二目的，我们通过AC场研究了DNA杂交的分子比对。最后，我们成功证明了电极之间DNA/PAN杂交的分子比对，以研究电子特性作为分子线。
