Synthesis and Characterization of New Metal-Free and Metal Phthalocyanines With Peripheral N′-2 Substituents
(John Wiley & Sons Ltd, 2001) Agirtas, MS; Bekaroglu, Ö
The synthesis of new metal-free and zinc(II), cobalt(II) phthalocyanines substituted with four 4-(2-N ' -cyanoethyl)aminoethylsulfanyl groups is described. The new compounds have been characterized by elemental analysis and IRI H-1 NMR and UV-vis spectroscopy. Copyright (C) 2001 John Wiley & Sons, Ltd.
Synthesis of Phthalocyanines Crosswise-Substituted With Two Alkylsulfanyl and Two Crown-Ether
(Natl inst Science Communication, 2001) Agirtas, MS; Sönmez, M; Kandaz, M; Bekaroglu, O
Crosswise-substutited phthalocyanines with two nitro and two dodecylsulfanyl groups are synthesized by a 1:1 condensation of 1,3-dihydro-1,3-diimino-6-(n-dodecylsulfanyl) isoimino indolenine with 6-nitro-1,3,3-trichloroisoindolenine in the presence of sodium methoxide, hydroquinone and triethylamine. Nitro substituents are reduced to amines by sodium sulfide and condensation of the amino groups with benzo-15-crown-5-aldehyde results in a new Pe with two benzo-15-crown-5-imino substituents. The compounds have been characterized by elemental analyses, UV/Vis and IR spectroscopy.
