In this thesis,using glycine or imidazole as the source of carbon dots?CDs?,two new kinds of CDs-Gly and CDs-Imidazole were obtained by the bottom-up approach,respectively.And based on the nano-characteristic structure characterization by FT-IR,NMR,TEM and PXRD et al and the examination of UV-Visible absorption and photoluminescence,their photophysical properties were checked.In the meantime,based on the color-tuning,CDs-Gly-grafted polymeric hybrid material and CDs-Imidazole with direct white-light were also obtained,respectively.Starting from CDs-Gly,4-vinylbenzyl chloride was used as surface modification agent by reacting with the amino-group of CDs-Gly in an alkaline environment to synthesize the polymerizable carbon dots PCDs-Gly.Meanwhile,through the self-assembly of the?-diketonate ligand HTTA?HTTA=2-thenoyltrifluoroacetone?,the vinyl-functionalized ancillary ligand 4-VB-FBI?4-VB-FBI=1-?4-vinylbenzyl?-2-?furan-2-yl?-1H-benzo[d]imidazole?and Sm?NO3?3·6H2O at a mole ratio of 3:1:1,the vinyl-containing complex monomer[Sm?TTA?3?4-VB-FBI?]was obtained.Moreover,using the PCDs-Gly and the complex monomer[Sm?TTA?3?4-VB-FBI?]as the polymerizable monomers,the PMMA-supported hybrid material Poly?MMA-co-?PCDs-Gly?-co-[Sm?TTA?3?4-VB-FBI?]?was obtained from their copolymerization with methyl methacrylate?MMA?in the presence of AIBN?azobisisobutyronitrile?.Furthermore,in dependence on the combination of the greenish blue-light from the grafted PCDs-Gly and the orange-light from the grafted complex monomer[Sm?TTA?3?4-VB-FBI?]within,the direct white-light was realized for the hybrid material Poly?MMA-co-?PCDs-Gly?-co-[Sm?TTA?3?4-VB-FBI?]?.With regard to CDs-Imidazole,the photophysical behavior effects of solvent?such as chloroform,THF or actone et al?and the exciting wavelength were examined,where direct white-light was also realized CDs-Imidazole in solution uponlex=365 nm. |
