▎ 摘　　要

Reduced graphene oxide (rGO) was obtained from graphene oxide (GO) by hydrothermal method. In order to easily synthesize hybrid compounds (HB1 and HB2), the carboxyl groups on the surface of rGO were converted to acyl chloride with SOCl2 and rGO-COCl was obtained. To use in the synthesize of the hybrids, two new carboxylic acid substituted multifunctional imine compounds ({(E)-4-((2-hydroxy-4-((1-(p-tolyl)-1 H-1,2,3-triazol-4-yl)methoxy) benzylidene)amino)benzoic acid (5), (E)-4-((2-hydroxy-4-((1-(4-methoxyphenyl)-1 H-1,2,3-triazol-4-yl)methoxy)benzylidene)amino)benzoic acid (6)}) were obtained and characterized by the H-1 and C-13(H-1)NMR, FT-IR, MALDI-TOF-MS techniques. The hybrids were obtained from the reaction of the imine and rGO-Cl compounds and characterized by the FT-IR, UV-Vis, emission (PL), X-ray diffraction (XRD), SEM-EDX and TEM methods. The chemosensor properties of the hybrids were investigated towards some metal ions (Al3+, Ag+, Co2+, Cr3+, Cu2+, Fe3+, Hg2+, Mn2+, Ni2+, Zn2+, Cd2+, Pb2+). At the short wavelength light, HB1 showed a blue sensor against Ag+, Co2+, Cu2+, Fe3+, Ni2+ and Pb2+ ions, dark green against Al3+, Zn2+ and Cd2+ ions, and purple-colored sensors against Hg2+ ions. HB2 hybrid material exhibited sensor properties against Ag+, Cr3+, Cu2+, Fe3+, Zn2+ and Cd2+ ions. At the long wavelength light, HB1 and HB2 materials showed sensory properties against Ag+, Cr3+, Cu2+, Fe3+, Zn2+ and Cd2+ ions. The hybrid HB1 has selective chemosensing properties against Al3+ and Hg2+ ions at the short wavelength light. In addition, the 1931 CIE (x,y) chromaticity coordinates of the hybrids and imine compounds were investigated and the x, y values of the compounds were found to be close to the National Television Standard Committee (NTSC) standard.
