英文摘要: This project aims to design and synthesize diverse arenesulfonic acids with different structural types, configurations and diverse substituent groups, which are then employed to construct metal-organic and supramolecular networks with novel topological structures and intriguing photoluminescent properties by the self-assemble or hydro(solvo)thermal reaction of rare earth metal ions, amine and well-designed arenesulfonic acids. By the syntheses of these complexes, we intend to investigate the influence of the factors, such as the pH value, solvents, configurations of the sulfonates, metal ions, structure of amines and their molar ratio to the sulfonic acids, on the final topological architectures. We would like to find the proper technical conditions for preparing arenesulfonate frameworks with excellent luminescent property and give rise to a summarization on the relationship among the assembly, structures and luminescent properties. Meanwhile, we probe the feasibility of these complexes acting as indicator to different toxic heavy metal ions and amines, which will provide reliable theory for the development of novel photoluminescent materials.
