A novel glycine-based Schiff base derivative (abbreviated as C16GlySb) containing long alkyl chain was synthesized from glycine reacted with 4-cetyloxy-2-hydroxybenzaldehyde and sequentially coordinated with various metal ions to give the corresponding metal complexes (abbreviated as G-M). The products were characterized by UV-Vis spectra and FT-IR spectra. At the same time, the thermal stability was measured by TG-DTA instrument. FT-IR analysis indicated that the nitrogen atom in imino group, oxygen atom in phenolic hydroxyl group, and carboxylic ion participated in coordinating with transition metal ion in doubly-bridged mode. UV spectra showed that compared with ethanol solution, the cast film on quartz plate showed H-type or J-type aggregate structure. In addition, the thermal stability of G-M had been obviously superior to that of the ligand C16GlySb. The present results have showed potential application in fields of functional material and catalyst.
