Design Synthesis And Properties Study Of Aromatic Sulfonic Acid Complexes

Recently,the continuous consumption of earth’s resources has caused a series of environmental pollution and energy crisis problems,and it is urgent to develop and convert more clean and sustainable resources.Researchers have been interested in complexes in various fields.Especially sulfonate has rich coordination modes,and have attracted more attention and widely used in catalysis and adsorption.In addition,the existing studies shows that complexes can also play an important role in the field of power output conversion.Triboelectric nanogenerator(TENG)is a kind of device that converts various mechanical energy into electrical energy output.As the friction layer material,the complex has good performance and can be used in sensing,which is advantageous not only for extending the advanced materials of TENG but also for expanding the application range of complexes.The research content of this paper mainly includes:The complex {[Co(bipy)(H2O)4][3-OH-2,7-NDS]}n(1)was prepared by Co(Ⅱ)with 3-hydroxy-2,7-naphthalenedisulfonate(3-OH-2,7-NDS)and 4,4’-bipyridine in the mixed solution of water and methanol via self-assembly,respectively.Complex 1 consists of 1D coordination electriferous linear chains of[Co(bipy)(H2O)4]2+and free 3-OH-2,7-NDS as counterions.As the friction material of TENG,it has high-output performance.In the practical application,it can light 1488 commercial green LEDs and drived an anticorrosion system to protect the metal from corrosion.The complexes {[Zn(bipy)(H2O)4][2,7-NDS]}n(2)and{[Zn(bipy)(H2O)4][3-OH-2,7-NDS]}n(3)were synthetsised via Zn(Ⅱ)with 2,7-naphthalenedisulfonate(2,7-NDS)and 3-hydroxy-2,7-naphthalenedi sulfonate(3-OH-2,7-NDS)and 4,4’-bipyridine in the mixed solution of water and methanol by self-assembly,respectively.The structures of complex 2 and 3 were resemble of the 1.The effect of functional group modification on the output performance was compared as friction materials of TENG.The results showed that hydroxyl modified complex 3 has high output performance,which provides a way to design high-output TENG friction layer materials.The complexes[Zn(2,7-nds)(bipy)(H2O)2]n(4)and[Zn2(3-OH-2,7-nds)2(bipe)(H2O)4]n(5)were synthetsised via Zn(Ⅱ)with 2,7-naphthalenedisulfonate(2,7-NDS)and 3-hydroxy-2,7-naphthalenedi sulfonate(3-OH-2,7-NDS)and 1,2-bis(4-pyridyl)ethylene in the mixed solution of water and methanol by self-assembly,respectively.Both of them are Zn(Ⅱ)and bipe form the main chain,and the sulfonate ligands are suspended on both sides.Complex 4 and 5 were used as TENG friction layer materials to test the output performance of the TENG.
