Abstract:

Two new porphyrin-Salen type ligands 5-(3-amino-4-(3,5-di-tert-butylsalicylidene)aminophenyl)- 10,15,20-triphenylporphyrin (1) and 5- (N,N'- di(3,5- di- tert- butylsalicylidene)-3,4-diaminophenyl)-10,15,20- triphenylporphyrin (2), their homo- and hetero- binuclear metal complexes and their mononuclear metal complexes were synthesized and characterized by 1H nuclear magnetic resonance (1H NMR) spectroscopy, electrospray ionization mass spectrometry (ESI-MS), elemental analysis, Fourier transform infrared (FTIR) spectroscopy, and ultraviolet visible (UV-Vis) spectroscopy. The third-order nonlinear optical properties of these ligands and complexes were investigated by Z scan techniques. Experimental results indicated that ligands 1 and 2 have a close strong reverse-saturable absorption and self-defocusing effect. The polarization induced by the coordinated metal ions affects the nonlinear refractive indexes of these ligands.

Key words: Porphyrin- Salen type ligand, Homo- and hetero- binuclear metal complexes, Spectrum property, Third-order nonlinear optical property, Z scan
