Synthesis,structures And Properties Of M/Pb/X(X=I,Br) Heterometallic Inorganic-organic Hybrid Polymers Constructed By Pb/X Inorganic Framework

Inorganic-organic hybrid polymer material based on Pb/X inorganic framework can combine the advantages of semiconductor inorganic materials, organic materials and semiconductor materials, It has been widely used in the fields of optical communication, light induced / electro luminescent materials, semiconductor integrated circuits, photovoltaic materials, biomedicine and so on.This paper in access do the research on heterometallic Pb/X hybrid polymers on the basis of a large number of domestic and foreign literature, Simultaneous introduction of nitrogen containing conjugated organic ligands and hybridmetal ions into Pb/X inorganic system and obtain the eight novel heterometallic Pb/X hybrid polymer(1~8) under solvothermal synthesis conditions.In complex 1~3, Complexation of cations as template, cation by weak hydrogen bonding and electrostatic interactions with anionic Pb/X framework unifies in together, the formation of single metal poly anion one-dimensional chain structure [MLn][PbxXy] type organic inorganic hybrid different metal polymers containing the metal ion and the ligand formation; complex 4-5, second metal ions directly connected with Pb/I inorganic clusters,formed Cu/Pb/I inorganic heterometallic cluster anion framework formation, these two Cu/Pb/I inorganic hybrid polymer network framework has never been reported in the literature, with great novelty and organic cation part in the overall structure of the static balance level role. In the compound 6-8, a cationic template is not required, and the ligand is connected the different metal ions to the Pb/I inorganic framework, which forms a complex type polymer, and the interaction force between the components is strong; At the same time,we also conjugated ligands and metal iodide(PbI2, CuI) directly, get two cases of in situ formation of new cationic structure of one dimensional chain compounds(9~10) and one case with novel 3D supramolecular structure with one-dimensional porous polymer(compound 11).We aim to introduce the heterometallic icons and organic ligands to Pb/X inorganic system in new hybrid polymer at the molecular level,and explore the effect of heterometallic ions were introduced to Pb/X inorganic framework construction, which do some basic research of the formation of the new semiconductor materials, molecular magnetic materials, optical materials and so on.
