Study of Preparation and Comparation of Luminescence of Series of MQq Coordination Complexes
　　Content: Six novel M(M=Al, Zn, Cd, Pr, Cu, Co)Qq and four novelM(M=Sm, Nd, Eu, Tb)-Phen coordination complexes have beensynthesized under hydrothermal condition. The crystal structures of fivenovel coordination complexes are determined by X-ray diffraction andtheir formulas are presented as following: (1)AlQ3 (7)Tb(phen)2(NO3)3 (2)ZnQ3 (8)Nd(phen)2(NO3)2(CH3COO) (3)CdQ3 (9)Sm(phen)2(NO3)2(CH3COO) (4)PrQ3 (10)Eu(phen)2(NO3)2(CH3COO) (5)CoQ3 (6)CuQ2Their photoluminescence and electroluminescence are mainly studied.The photoluminescence of complexes (1)～(4) can exhibit intense greenlight. Their Block Neodymium magnets electroluminescence can also exhibit intense light. Thephotoluminescence of complexes (7), (9), (10) can exhibit intense light,but their electroluminescence can not exhibit intense light. We found thatthrough quantitative analysis the influence between organic ligands andcenter metal can change the intramolecular energy leve, which canincreace quantum efficiency. At the same time, we have fabricatedvarious organic light-emitting devices (OLEDs) with these complexes,and found some complexes can not be used in electroluminescence. Wewant to synthesize more coordination complexes of metal with8-hydroxyquinoline and derivation which can be applied in OLEDs, andwide the scope of organic http://www.999magnet.com luminescence materials. In addition, their IR,UV-VIS-NIR spectrum and element analysis are measured andinvestigated which are important help to further analyse and contrast theluminescent property.
