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，这些涂层将使纳米显微镜的各种应用成为可能，其分辨率超出当今显微镜和光谱学的技术水平。为了实现这一目标，我们将与各方密切合作。有机化学研究所和物理化学研究所，他们以自己的项目提案参与了这个提案包。光致变色涂层已经在与光刻工艺相关的文献中描述过，它们被称为吸附调制层 (AML) 为新的纳米技术设想的高分辨率和图像质量需要相当薄且高效的 AML，预计厚度为 100 nm，比 2017 年发表的最先进涂层还要薄。文献的系数为 4。此外，AML 需要合适的粘度、导热性和光致变色稳定性，因为要在衍射极限区域内进行多次测量才能获得最高分辨率的图像，需要防止光致变色分子的光致旋转（即所谓的“烧孔”）等次级效应，所有这些效应主要取决于光致变色分子周围的环境，并且应通过开发合适的交联、无定形基质。光致变色分子将被施加到液相内的表面，以便在该液体膜内受到保护。随后，将使用非热等离子体来聚合该膜。文献，以及应扩展以提供所需的 AML 功能。应利用和优化这些特殊等离子体聚合物的弹性、拉伸性能或内部粘度，从而使分子发生几何形状的变化。这些过程还应包括专门定制的交联反应，此外，将引起物理和化学性质的梯度，使得表面表现出适合非接触式测量的抗反射行为或适合的表面硬度和。使用浸没物镜进行测量的稳定性。
