We propose a hierarchical self-assembly of multifunctional molecular architectures, in which bricks bearing different functionalities (magnetic, electronic, or photophysical) are organized through non-covalent electrostatic interactions into higher-order structures. By carefully choosing the molecular building blocks, we will prepare a hybrid hierarchically-organised material that exhibits at least two physical properties which are difficult or impossible to achieve concomitantly by other means. Using this approach, challenging combinations of physical properties and new physical phenomena can be envisioned, which point towards potential applications in molecular electronics, spintronics and optotronics. The different physical functionalities to combine will be located on positively and negatively charged molecular building blocks [M-][C+], which are expected to self-assemble by electrostatic interactions to molecular architectures of increased structural complexity (e.g. stacks, pillars, sheets, etc.) We will explore the possibilities provided by a molecular approach to build multifunctional (photo)magnetic conductors and superconductors as hybrid materials formed by organic cation-radicals (TTF derivates), cationic dye molecules (e.g. Rhodamine compounds) and single-molecule magnet anions (e.g. of the [Ln(Pc)2]- -family). The interplay between physical and structural properties will be investigated in detail, where new physical phenomena could be present.

我们提出了一种多功能分子结构的分层自组装，其中具有不同功能（磁性、电子或光物理）的砖块通过非共价静电相互作用组织成更高阶的结构。通过仔细选择分子构件，我们将制备一种混合的分层组织材料，该材料具有至少两种物理特性，而这些物理特性很难或不可能通过其他方式同时实现。使用这种方法，可以设想具有挑战性的物理特性和新物理现象的组合，这指向分子电子学、自旋电子学和光电子学中的潜在应用。要组合的不同物理功能将位于带正电和带负电的分子构建块 [M-][C+] 上，预计这些分子构建块将通过静电相互作用自组装成结构复杂性增加的分子结构（例如堆叠、柱、片等）。我们将探索分子方法提供的可能性，以形成混合材料来构建多功能（光）磁导体和超导体 由有机阳离子自由基（TTF 衍生物）、阳离子染料分子（例如罗丹明化合物）和单分子磁性阴离子（例如 [Ln(Pc)2]- - 家族）组成。将详细研究物理特性和结构特性之间的相互作用，其中可能会出现新的物理现象。
