摘要

受控机制。在人工超分子系统中,最近的进展使人们能够对分子识别行为和自组装过程进行大量的研究。虽然它们通常是热力学控制的事件,但对这些过程的动力学控制对于开发新的超分子功能系统至关重要。在这里,我们构建了基于配位化学的动力学控制的新型超分子配合物。宿主-客体系统的客体吸收/释放可以通过将可更换的帽引入大环金属宿主的孔中来精确控制。动力学研究还揭示了宿主阵风结合的机制,其中金属宿主在宿主反应的同时吸收客体阳离子。通过使用引入螯合配位位点的刚性弯曲配体,我们通过模板定向自组装实现了动力学稳定的五核金属纳米带的选择性形成。

Development of Kinetically Controlled New Functional Supramolecular Complexes
controlled mechanisms. In artificial supramolecular system, the recent advances have allowed numerous studies of molecular recognition behaviors and self-assembly processes. While they are generally thermodynamically controlled events, kinetic control of such processes is essential for the development of new supramolecular functional systems. Here we constructed kinetically controlled new supramolecular complexes based coordination chemistry. The guest uptake/release of host-guest system can be precisely controlled by the introduction of replaceable caps into the apertures of the macrocyclic metallohost. The kinetic study also unveiled the mechanism of host-gust binding where the metallohost uptakes the guest cation accompanied by the host reaction. By using a rigid bent ligand in which chelate coordination sites are introduced, we achieved the selective formation of kinetically-stable pentanuclear metallonanobelt by template-directed self-assembly.
