Dynamic combinatorial chemistry is a novel aspect of supramolecular chemistry dealing with the generation of dynamic libraries resulting from all the possible combinations of fragments of the constituents (keys). The receptors (locks) favour the expression of the keys that bind best to it (thermodynamic selection) or that form fastest within it (kinetic selection). The already mentioned in situ rich chemistry of the organosulfur ligands makes this system suitable for developing supramolecular dynamic combinatorial aspects under solvothermal conditions.Moreover, these kinds of organosulphur ligands seem to be especially suitable to form metal–sulphur–organic networks with promising electronic properties.The incorporation of thiolate-S as a single atom bridge between adjacent transition metal sites could allow higher spin density delocalization towards the bridging atom and contribute to strong super-exchange interactions when the selected metal orbital energies are better matched for the sulphur atom. In principle, this beneficial feature is highly desirable in terms of magnetic, conductive and luminescent properties of the resulting materials.

动力组合化学是超分子化学的一个新型学科, 目的在于通过化学成分碎片(钥匙)的所有可能组合方式建立动态文库. 受体(锁)倾向于接受最合适的钥匙构象,这种钥匙或者是最易结合(热力动力学选择)的构象,或为最易形成的构象(运动学选择)。 热溶剂条件下,有机硫配体原位富集化学与这门超分子动态组合学科的开发需求极度契合。这种有机硫配体似乎特别倾向形成具有理想电荷的有机铁硫网。相邻过渡态铁原子以硫醇S单原子相连,可以保证连接原子更高的旋转密度分布,以便使目标金属原子的旋转能与硫原子通过强大的超交换作用达到更高的匹配。原则上,最终产物在磁学,电导学,发光特性方面都具有高度倾向性的特点。
