We have synthesized a novel liquid crystalline phthalocyanine(Pc)-fullerene(C60) dyad (C14S)6PcCu-VAN-C60 (3a) bridged by an inexpensive natural product of vanillin (VAN), instead of the previous long n-alkylene chain spacer. We have also synthesized a co

A new highly fluorescent difluoroboradipyrromethene (BODIPY) dye (4) bearing an phthalonitrile group at meso-position of the chromophoric core has been synthesized starting from 4-(4-meso-dipyrromethene-phenoxy)phthalonitrile (3) which was prepared by the

A phthalocyanine (4) with four salicylhydrazone ligating groups that are directly linked through oxygen bridges to the macrocyclic core has been synthesized by condensation of tetrakis(4-formylphenoxy)phthalocyaninato zinc(II) (3) with salicylhydrazine. Salicylhydrazine was crystallized in methanol during the synthetic procedure. The crystal structure has triclinic space group P-1 with a?=?5.8292(6) ?, b?=?7.3039(7) ?, c?=?17.9798(18) ?, α?=?84.272(8)°, β?=?89.184(8)°, γ?=?81.469(8)°, and Z?=?4. Intramolecular O–H?O and intermolecular O–H?O, N–H?N, N–H?O hydrogen bonds were determined in the crystal structure. In addition, there is a weak C–H?π interaction. Complexation on the periphery to yield tri-nuclear Zn(II)Pcs (5–7) was performed through the reaction of a Schiff base-substituted phthalocyanine (4) with MnCl2·4H2O, CoCl2·6H2O, or Ni(OAc)2 salts. Fourier transform infrared, 1H NMR, 13C NMR, UV–Vis, ICP-OES (inductively coupled plasma optical emission spectroscopy), mass spectroscopies, and elemental analyses were applied to characterize the prepared compounds. Bleach catalyst activity of the prepared phthalocyanine complexes (5–7) was examined by the degradation of morin and curcumin, respectively. The catalysts had better activity for color removing in solutions at ambient temperature than to that of tetraacetylethylenediamine (TAED).

A simple and efficient synthesis of novel zinc(II) phthalocyanines bearing triazole moieties was described. The synthetic approach for preparation of the phthalocyanines 1 and 13 was achieved by Schiff base condensation reaction of phthalocyanine tetracarbaldehydes 3 and 12 with 4-amino-4H-1,2,4-triazole 5 in tetrahydrofuran in reasonable yields. The photophysical and photochemical properties of the compounds 1, 3, 12 and 13 were recorded only in DMSO. The singlet oxygen generation ability of the targeted phthalocyanine Schiff bases were investigated in an attempt to understand their potential for photodynamic therapy (PDT) activity. Moreover, in vitro PDT application was performed against the MCF-7 and MDA-MB-231 invasive breast carcinoma cell lines. Preliminary assay showed that the compounds 1 and 13 possessed the phototoxicity and cytotoxicity, with a maximum of 30% MCF-7 cells dead following light irradiation. It was also revealed that the targeted phthalocyanines possess promising characteristic as photosensitizer towards tumor cells.
