A-B block copolymers with block lengths in the range that induces nanophase-separation with the formation of cylindrical domains of polymer A in the matrix of polymer B will be prepared as thin films on solid substrates. Solvent-annealing will allow for the generation of patterns with a high degree of long range positional and orientational order. The resulting regular arrays of cylindrical domains with (tunable) diameters and separation distances in the nanometer range, and oriented normal to the substrate surface, will be used as templates for the fabrication of arrays of nanorods or nanowires from different types of materials, including (noble) metals, oxides, semiconductors, or conducting/redox-active polymers. MOCVD and wet chemical protocols for this growth of nanorod arrays will be employed and evaluated. Of the wide range of interesting physical properties that these nano arrays have, we will focus on their optical (linear, nonlinear and integrated) properties with an emphasis on surface plasmon optical investigations, as well as on using the structures for the diffractive optics. Additionally, the high surface area of these arrays will be used to generate binding matrices for bioaffinity studies covalently coupling ligands (peptides or oligonucleotides) via silane- (for SiO2) or thiol- (for Au, Ag GaAs) derivatization.

嵌段长度在诱导纳米相分离并在聚合物B的基质中形成聚合物A的圆柱形域的A-B嵌段共聚物将被制备为固体基底上的薄膜。溶剂退火将允许生成具有高度长范围位置和方向顺序的图案。由此产生的圆柱形域的规则阵列，其直径和间隔距离在纳米范围内，并且垂直于基底表面，将用作由不同类型的材料（包括（贵）金属、氧化物、半导体或导电/氧化还原活性聚合物）制造纳米棒或纳米线阵列的模板。将采用和评估用于纳米棒阵列生长的 MOCVD 和湿化学协议。在这些纳米阵列具有的各种有趣的物理特性中，我们将重点关注它们的光学（线性、非线性和集成）特性，重点是表面等离子体光学研究，以及使用衍射光学结构。此外，这些阵列的高表面积将用于生成用于生物亲和力研究的结合基质，通过硅烷-（对于SiO2）或硫醇-（对于Au、Ag GaAs）衍生化共价偶联配体（肽或寡核苷酸）。
