A yellow-fluorescent hydrotalcite-like(HTlc) composite,Zn-(HQ-4-biPh)-HTlc,was prepared by a one-pot synthesis. In this composite,the magnesium(Ⅱ) was partially replaced by zinc(Ⅱ) in the hydrotalcite-like layers and 2-biphenyl-4'-yl-8-quinolinolato was dispersed into the anions among the interlayer region to coordinate the zinc(Ⅱ) ion through its oxygen and nitrogen atoms. The structure,morphology,and optical properties of the composite were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),FT-IR spectroscopy,thermogravimetry(TG) and photoluminescence(PL). Compared with Zn[2-(p-biph)-8-Q-O]₂,the resultant composite Zn-(HQ-4-biPh)-HTlc exhibits much stronger fluorescence and higher thermal stability,although the contents of metals and ligands were decreased greatly. Thus,Zn-(HQ-4-biPh)-HTlc is a promising yellow-fluorescent material for applications in the photoelectronic area.
