Abstract

A sextuple-decker heteroleptic phthalocyanine heterometallic compound (1) with a subunit arrangement of {(Pc)Sm(Pc)Cd(Pc*)Cd(Pc*)Cd(Pc)Sm(Pc)} has been prepared and analyzed using various spectroscopic instruments, in which four unsubstituted phthalocyanine anions (Pc) and two substituted analogues (Pc*) with -pentoxyl substituents at eight peripheral positions are connected through the complexation of two Sm(III) and three Cd(II) ions. In particular, its sextuple-decker structure has been disclosed by the single-crystal X-ray diffraction technique. The solution and gel glass forms of this compound display third-order nonlinear optical properties due to the intrinsic conjugated nature over the sextuple-decker sandwich complex.

摘要

一种具有{(Pc)Sm(Pc)Cd(Pc*)Cd(Pc*)Cd(Pc)Sm(Pc)}亚基排列的六层杂配酞菁异金属化合物(1)已被制备，并使用各种光谱仪器进行了分析，其中四个未取代的酞菁阴离子(Pc)和两个在八个外围位置带有-戊氧基取代基的取代类似物(Pc*)通过两个Sm(III)和三个Cd(II)离子的络合连接。特别地，其六层结构已通过单晶X射线衍射技术揭示。由于在六层夹心配合物上的固有共轭性质，该化合物的溶液和凝胶玻璃形式显示出三阶非线性光学性质。
