Synthesis and characterization of new phthalocyanines containing four 15-membered tetrathiaoxa macrocycles
Agar, E; Sasmaz, S; Akdemir, N; Keskin, I (Marcel Dekker Inc, 1999)A straightforward and generalizable synthesis of metal-free (H-2) and metal derivatives (M = Ni, Co or Zn) of a symmetrically tetrasubstituted phthalocyanine derived from tetrathiooxaphthalonitrile is described. All of ... -
Synthesis and characterization of new phthalocyanines containing thio-oxa-ether moieties
Sasmaz, S; Agar, E; Akdemir, N; Keskin, I (Elsevier Sci Ltd, 1998)Metal-free and metal phthalocyanines (M:H-2, Ni, Co, Zn) 4-7 containing four 9-membered dithiaoxa macrocycles were prepared. The new compounds were characterized by elemental analyses, and IR, H-1-NMR, UV-VIS and DTA. The ... -
Synthesis and characterization of new tetraaza-bridged polymeric phthalocyanines
Agar, E; Sasmaz, S; Keskin, I; Akdemir, N (Elsevier Sci Ltd, 1998)New tetraaza-bridged metal-free and metal phthalocyanine polymers were prepared. The metal-free phthalocyanine polymer was obtained by the reaction of 4,4'-(octane-1,5,8,12-tetra-p-tolysulphonyl-1,5,8,12-tetraamine)-diph ... -
Synthesis and characterization of novel phthalocyanines containing four 15-membered oxadithiadiaza mixed-donor macrocycles
Agar, E; Sasmaz, S; Akdemir, N; Keskin, I (Royal Soc Chemistry, 1997)Symmetrically tetrasubstituted metal-free and metal phthalocyanines (M = 2H; Cu, Ni, Co, Zn or Fe) with four 15-membered heteroatom (N, O, S)-containing donor sites attached have been synthesized and characterized:by: ... -
Synthesis and properties of 1,5-dithio-3-oxa-pentanediyl bridged polymeric phthalocyanines
Agar, E; Sasmaz, S; Keskin, I; Karabulut, B (Elsevier Sci Ltd, 1997)Oxa-thio bridged metal-free and metal phthalocyanine polymers were prepared. Metal-free phthalocyanine polymer (H2Pc) and metal phthalocyanine polymers (Ni, Cu, Co, Zn or Fe) carrying dithio-oxa bridged were synthesized ...
