11. Summary of the new findings of the thesis

- Successfully synthesized 9 thiosemicarbazone ligands bearing anthracene/pyrene and 28 metal complexes of Ni(II), Cu(I), Cu(II), Zn(II), Pd(II).

- The ligands and complexes were characterized by physical methods such as IR, ESI-MS, và 1H-NMR. 5 ligands and 22 complexes were structurally determined by SC-XRD.

- Various coordination geometries and steric influence induced by substituents of thiosemicarbazone ligands were observed.

- Photophysical properties of the ligands and complexes were studied by absorption and photoluminescence spectroscopies.

12. Practical applicability, if any: The Ni(II), Pd(II) complexes with anthracene- and pyrene-based ligands are strongly emissive. Hence, they may be used to detect anions, explosive nitro aromatic compounds via fluorescence quenching mechanism. As having large conjugated systems of anthracene and pyrene, the complexes may interact effectively with DNA via π-π stackings.

13. Further research directions, if any:

- DNA binding study of the complexes;

- Fluorescent sensing of anions and explosive nitro aromatic compounds.
