The project addresses the interdisciplinary coordination and physicochemical aspects of the as-yet-underdeveloped class of polyoxometalates (POMs) derivatized with phthalocyaninato (Pc)-supported transition metal / lanthanide moieties. The crucial structural feature to be developed is the direct grafting of metal–Pc moieties onto the lacunary POM core. The resulting hybrid compounds are expected to exhibit a variety of valuable properties at the level of individual molecules in solution and in the solid state and in the form of their self-assembled monolayers (SAMs) on (semi-)conductive surfaces. The exceptional interplay between the molecular POM charge and the POM redox and/or magnetic states that are combined with the redox activity of Pc ligands and the paramagnetism of metal–Pc moieties is called to help identify diverse perspectives for controlled manipulation of charge transport through the incorporated d- and f-states in tunnel junctions. The diffraction, spectroscopic, magnetochemical, surface-sensitive and quantum mechanical methods will be used to gain in-depth insights into the processability of synthesized heteroleptic metal complexes toward two-dimensional monolayers, their compatibility with different conductive and semi-conductive surfaces, and the electrical triggering of stimuli-responsive states of SAMs. The findings of this cross-disciplinary investigation aim to boost further progress in the area of molecular electronics and spintronics, with the eventual goal to enable technology transfer and commercialization of the fundamental efforts to practical molecule-based computer memory devices.

该项目解决了尚未开发的一类多金属氧酸盐（POM）的跨学科协调和物理化学方面的问题，该多金属氧酸盐（POM）是由酞菁（Pc）支撑的过渡金属/镧系元素衍生的，待开发的关键结构特征是金属的直接接枝。将 Pc 部分连接到缺位的 POM 核心上，所得杂化化合物有望在溶液和水中的单个分子水平上表现出多种有价值的特性。固态及其在（半）导电表面上的自组装单层 (SAM) 分子 POM 电荷和 POM 氧化还原和/或磁性状态之间的特殊相互作用，与 Pc 的氧化还原活性相结合。配体和金属-Pc部分的顺磁性有​​助于确定通过隧道结中的d-和f-态控制电荷传输的不同视角。磁化学、表面敏感和量子力学方法将用于深入了解合成的杂配金属配合物对二维单层的可加工性、它们与不同导电和半导体表面的兼容性以及刺激的电触发。这项跨学科研究的结果旨在促进分子电子学和自旋电子学领域的进步，最终目标是使技术转让和商业化的基础进一步努力付诸实践。基于分子的计算机存储设备。
