混合配体配位聚合物的设计、合成及光、磁性能的研究

摘要

Polyazolateucleobase-polycarboxylate-based coordination polymers(CPs)were designed and synthesized and their optical/magnetic properties were systematically investigated. The number and position of the carboxylate coligand and substituent type significantly govern the overall structures of the resulting CPs. A new synthetic method of efficient preparation of nucleobased-based CPs was developed,which helps to fully investigate the binding modes of the nucleobases and transition metal ions. Additionally,the alternating deprotonation of the mixed ligands was found playing an important role in controlling stepwise crystallization process,which provides a new approach for the polynuclear cluster-based metal complexes and the advance of the development of CPs.%开展了多氮唑/核酸碱基-多羧基混合配体配位聚合物的设计、合成方法及光、磁性能的结构性能调控研究工作。发现了混合配体配位聚合物的合成中，共配体对配合物结构调控的规律。发展了合成核酸碱基配位聚合物的新方法，完善了它们与金属离子的键合模式。揭示了混合配体交替去质子控制配合物的逐步结晶过程，为高核簇功能配位聚合物的可控构筑开辟了新方法，推动了配位聚合物化学研究的进展。
