摘要:

设计合成了两种新型卟啉-Salen 型配体5-(3-氨基-4-(3,5-二叔丁基水杨醛基)-氨基苯基)-10,15,20-三苯基卟啉(1)和5-(N,N’-二(3,5-二叔丁基水杨醛基)-3,4-二氨基苯基)-10,15,20-三苯基卟啉(2)及其同、异双核金属配合物和单金属核配合物. 采用氢核磁共振(1H NHR)谱、电喷雾质谱(ESI-MS)、傅里叶变换红外(FTIR)光谱和紫外-可见(UV-Vis)光谱等手段对各目标化合物进行了表征. 用Z扫描技术研究了配体及其金属配合物的三阶非线性光学性质. 实验结果表明:配体1和配体2具有相似的光学特征,均具有反饱和吸收的特性和自散焦效应;当不同的金属离子嵌入配体形成单、双核金属配合物后,分子的极性发生改变,他们的光学特性均受到影响.

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
