新型双8-羟基喹啉配体及其锌、铝配位聚合物的合成和性能
Synthesis and Properties of Novel Bis-8-Hydroxyquinoline Ligands and Zn(Ⅱ), Al(Ⅲ)Coordination Polymers
摘要
Abstract
Two novel ligands,3,5-bis(4-(8-hydroxyquinoline-5-methyleneamino)phenoxy)octyl benzoate(B8HQO)and 3,5-bis(4-(8-hydroxyquinoline-5-methyleneamino)phenoxy)hexadecyl benzoate(B8HQH)were synthesized and coordinated with Zn(Ⅱ)and Al(Ⅲ),respectively,to get the four corresponding coordination polymers(B8HQO-Zn,B8HQH-Zn,B8HQO-Al and B8HQH-Al).Their structures and properties were characterized by elemental analysis,Fourier transform infrared spectrometer(FTIR),UV-visible absorption(UV-Vis),proton nuclear magnetic resonance spectroscopy(1 H NMR),inductively coupled plasma optical emission spectroscopy(ICP-OES),thermal gravimetric analyzer(TGA)and fluorescence spectroscopy.The results indicate that compared with B8HQO and B8HQH,the solubility of the four coordination polymers is reduced,but can be partially soluble in N,N-dimethyl formamide(DMF),N,N-dimethyl acetamide(DMAC),dimethylsulfone(DMSO),N-methylpyrrolidone(NMP).The 5％mass loss temperatures of zinc and aluminum coordination polymers at around 378 and 364 ℃,respectively,show that they have good thermal stability.The fluorescence measurement shows that they emit green luminescence at 478～502 nm in DMF solution(3 ×10-5mol/L)and their fluorescence quantum efficiency is 28％～37％.The four coordination polymers emitting strong green luminescence at 528～553 nm in the solid state show that they have good luminescent properties.关键词
