In this project, we will develop, optimise and analyse photochromic coating systems. These coatings shall render possible various applications of the nanoscopy with resolutions beyond today’s state of the art for microscopy and spectroscopy. In order to achieve this goal, we will closely collaborate with the Institute of Organic Chemistry and the Institute of Physical Chemistry, who participate in this proposal package with their own project proposals.Photochromic coating are already described in the literature related to lithographic processes, where they are call adsorbance-modulaytion layers (AML). The high resolution and image quality envisioned for the new nanoscopic techniques require rather thin and efficient AML, with the projected thickness of 100 nm being thinner than the best state-of-the-art coating published in the literature by a factor of 4. Further, the AML requires a suitable viscosity, thermal conductivity and photochromic stability. Since multiple measurements will be taken within a diffraction-limited area in order to achieve images at highest resolutions, secondary effects such as optically induced rotation of photochromic molecules, so-called "hole burning", need to be prevented. All such effects are dependent mainly on the environment around the photochromic molecules, and shall be minimized by developing a suitable cross-linked, amorphous matrix.The photochromic molecules will be applied to the surface within a liquid phase, in order to be protected within this liquid film. Subsequently, the films will be polymerised using a non-thermal plasma. This approach has already been described and demonstrated in the literature, and shall be extended to deliver the desired AML functionalities. The typical properties of these special plasma polymers shall be exploited and optimized for their elasticity, tensile properties or inner viscosity. Thereby, the coatings will allow for the changes in geometrical shape, which the molecules undergo upon photochromic switching. These processes shall also include specifically tailored cross-linking reactions. Further, a gradient of physical and chemical properties will be induced such, that the surface exhibits a suitable anti-reflex behaviour for contactless measurements or a suitable surface hardness and stability for measurements using immersion objectives.

在这个项目中，我们将开发，优化和分析光致变色涂层系统。这些涂层应以除当今最新的显微镜和光谱状态以外的分辨率来使纳米镜检查可能采用各种应用。为了实现这一目标，我们将与有机化学研究所和物理化学研究所进行密切合作，他们通过自己的项目提案参加了此提案包。Photochromic涂层已经在与光刻过程有关的文献中已经描述了，在该过程中，它们是called call callbance-callbance-collbance tosorbance-tosemodemation layers（aml）。新的纳米镜技术所设想的高分辨率和图像质量需要相当薄，有效的AML，其预计厚度为100 nm的厚度比文献上发表的最佳最先进的涂层较薄。此外，AML需要合适的粘度，导热率和光导剂稳定性。由于将在衍射限制的区域内进行多次测量以在最高分辨率下实现图像，因此需要防止次要效应（例如光诱导的光致变色分子旋转），即所谓的“孔燃烧”。所有这些效果主要取决于光致变色分子周围的环境，应通过开发合适的交联无定形基质来最大程度地降低光色素分子，将在液相内应用于表面，以便在该液体中受到保护。随后，使用非热等离子体将膜聚合。在文献中已经描述和证明了这种方法，并应扩展以提供所需的AML功能。这些特殊的等离子体聚合物的典型特性应因其弹性，拉伸特性或内粘度而进行探索和优化。因此，涂料将允许几何形状的变化，分子在光致变色时会经历。这些过程还应包括专门定制的交联反应。此外，将诱导物理和化学特性的梯度，以使表面表现出适当的反反射行为，可用于非接触式测量或适当的表面硬度和稳定性，用于使用浸入目标进行测量。
