有机磁性材料领域的一个主要目标是制备高自旋分子化合物作为铁磁体的关键构件。1制备这些体系的两种众所周知的策略是拓扑准则2-4和自旋载流子的正交排列。在杂环π体系中，我们的注意力来自于分子π结构的结果，该结构既包括由三(2，4，6-三氯苯基)甲基自由基衍生的高稳定的内置自由基，也包括由混合的吡咯/噻吩三聚体组成的易于掺杂的嵌段。在这种背景下，观察到了对位排列π-体系中具有高度多重性的稳定状态的分子物种。6.
One main objective in the field of organic magnetic materials is the preparation of high-spin molecular compounds as key building blocks for ferromagnets. 1 The two well-known strategies to prepare these systems are the topological criterium2-4 and the orthogonal alignment of spin carriers. 3c, 5Our attention in the heterocyclic π-systems comes from the results obtained with molecular π-structures that accommodate both built-in radicals of high stability, derived from tris (2, 4, 6-trichlorophenyl) methyl radical, and easily doped blocks, made up by mixed pyrrol/thiophene trimers. In this context, molecular species with stable states of high multiplicity in a para arrangement π-system have been observed. 6
