摘要

Two heteroleptic corrole-phthalocyanine europium triple-decker complexes were fabricated into organic nanostructures by the standard phase-transfer method. The investigated compounds are represented by Eu-2(Pc)(2)[Cor(CIPh)(3)] (1) and Eu-2[Pc(OC8H17)(8)](2)[Cor(CIPh)(3)] (2), where Pc represents the dianion of phthalocyanine and Cor(CIPh)(3) the trianion of 5,10,15-tri(4-chlorophenyl)corrole. Both compounds 1 and 2 show typical electronic absorption spectra for a non-aggregated molecular structure in chloroform or toluene. However, in methanol compound 1 self-assembled into belt-like nanostructures while compound 2, which possesses long OC8H17 alkoxy side chains, self-assembled into large scale sheet-like nanostructures. The third-order nonlinear optical properties of both triple-decker compounds were also investigated in toluene by the Z-scan technique and characterized as showing nonlinear reverse saturation absorption and self-defocusing behavior. A third-order nonlinear optical susceptibility, chi((3)), of 3.18 x 10(-10) and 3.35 x 10(-10) esu was obtained for 1 and. 2, respectively, thus indicating the potential application of these compounds in the field of optical devices.
