Assemblies And Photocatalytic Properties Of Coordination Polymers Constructed From Aromatic Carboxylic Acid Ligands

Coordination polymers(CPs)constructed by aromatic dicarboxylic acid ligands are superior in luminescence,photocatalysis,adsorption,and electrochemistry.In this thesis,ten CPs based on benzenedicarboxylic acid as well as its derivatives and 1,4-naphthalenedicarboxylic acid and diverse substituted bis(benzimidazole)ligands were synthesized under hydrothermal conditions.All CPs had been determined by X-ray diffraction analysis,elemental analysis,IR spectra,and thermogravimetric analysis and so on.Then,luminescence properties and catalytic activities were discussed.The main content of this thesis includes the following three parts:The Chapter 1:The research progress and the influence factors of the CPs were introduced.Reviews on the research development of CPs containing of the benzenedicarboxylic acid and 1,4-naphthalenedicarboxylic acid were also briefly depicted.The development potential of CPs as photocatalysts was summarized.The Chapter 2:By using benzenedicarboxylic acid derivatives to react with transition metal in the presence of bis(benzimidazole)ligands,we got five CPs.Both CPs 1 and 2 are 1D chain and could form 3D supramolecular structures through hydrogen bondings.The CP 3 is a 2D(4,4)layer structure.CP 4 is a 3D 3,5T1 framework and CP 5 is a 3D sqc182 topology.CPs 2~5 are excellent candidates as photocatalysts in decomposing MB under UV light irradiation.In addition,CP 1 can efficiently adsorb Congo red,and the adsorption capacity is up to 297 mg/g under optimal conditions.The Chapter 3:CPs 6~10 based on 1,4-naphthalenedicarboxylic acid were synthesized.CP 6 and 7 possess 2D 3,5L2 network.CP 8 and CP 9 are 1D chain.CP 8 expands the 1D chain into a 3D supramolecular structure.CP 10 possesses a 3D two-fold interpenetrating cds topology.Figure 73;Table 13;Reference 79...
