摘要:An optically active phthalocyanine derivative with eight (S)-2-methylbutoxy moieties linked on α-position is originally synthesized. Through electronic absorption, circular dichroism (CD), fluorescence spectra, scanning electron microscopy (SEM) and X-ray diffraction (XRD) technique, its helical self-assembly and nonlinear optical properties are comparatively investigated with its analogous which has the same chiral moieties linked on β-position substitutions. Although these two complexes possess the same chiral functional group, they exhibit different CD signals in the Q absorption region of corresponding complex and self-assemble into different morphologies. One self-assembles into right-handed ribbon-like aggregates while the other one is left-handed fibers. In addition, both complexes show good third-order nonlinear optical property. © 2015 Elsevier B.V. All rights reserved.
