多层三明治型四吡咯基金属配合物的研究进展

Research Progress on Sandwich-Type Multiple-Decker Tetrapyrrole-Based Metal Complexes

受合成方法的制约,对于三明治型四吡咯基金属配合物的研究长期局限于相应的双层及三层化合物。自2010年以来,通过将中性态双层稀土配合物与二价镉离子在一定条件下聚合,成功得到四层,五层和六层四吡咯金属化合物。本文从合成方法、晶体结构、单分子磁体性质及三阶非线性光学性质等方面,对这一类新型的多层三明治型四吡咯基金属配合物的研究进展进行了总结,并期待它们在新型分子功能材料研究领域包括磁光、磁手和光电复合功能分子材料方面取得令人鼓舞的新进展。

Studies of sandwich-type tetrapyrrole metal complexes were retarded at the double- and triple- decker species for a long time due to the limitation on the synthesis method. The condensation of correspond- ing neutral bis （tetrapyrrole） rare earth （III） double- decker compounds in the presence of cadmium salt led to the isolation of quadruple-, quintuple-, and sextu- pie-decker complexes since 2010. This article tries to briefly summarize the progress achieved in this direc- tion with the emphasis on the synthesis, structure, single- molecule magnetic, and nonlinear optics prop- erties of novel multiple-decker sandwich-type tetrpyr- role metal complexes. Future efforts in this field are expected to lead to novel multi-functional molecular materials including magneto-optical, magneto-chiral, and photo-electric molecular materials
