We investigate almost planar compounds where one to three redoxactive centers are connected to a central, likewise redox-active triangular core. Mixedvalent forms, where only part of the redox sites are oxidized to paramagnetic sites, will be investigated with respect to the degree of valence delocalization or electronic bistability by molecular spectroscopy in solution. The behaviour of ensembles of molecules in solution will then be compared to that of individual molecules deposited on surfaces and studied by scanning probe microscopy and spectroscopy. A further point of interest is the coupling pattern of unpaired spins and the magnetic properties of states where several paramagnetic sites are pre-sent within the same molecule.

我们调查几乎平面的化合物，其中一到三个氧化还原活性中心连接到一个中央，同样氧化还原活性的三角形核心。混合价的形式，其中只有部分的氧化还原位点被氧化为顺磁性网站，将进行调查相对于在溶液中的分子光谱的价离域或电子双稳态的程度。然后将溶液中分子集合的行为与沉积在表面上的单个分子的行为进行比较，并通过扫描探针显微镜和光谱学进行研究。感兴趣的另一点是未成对自旋的耦合模式和在同一分子内存在几个顺磁位点的状态的磁性。
