“…Phthalocyanines have recently received much attention, especially because of their synthetic [1] and structural aspects [2], spectral properties [3], electrochromic behaviour [4] and electrical conductivity [5]. For the broad range of applications, the stable phthalocyanine core should be amenable to modifications which can be accomplished either by changing the central metal ion or by adding functional groups on the periphery [6].…”

1,7-dithia (12-crown-4)-bridged phthalocyanine network polymers were prepared from tetracyanodibenzo-[1,7-dithia(12-crown-4)]. In addition, the synthesis of two 1,7-dithia (12-crown-4) linked peripherally octa-substituted dimeric phthalocyanines, which contain a combination of hexakis(alkylthia) side chains, is described. These extremely soluble compounds were prepared by the condensation of an iminoisoindoline derivative and a subphthalocyanine. The novel compounds are characterized by elemental analyses, UV/vis, IR, mass, 1 H NMR and 13 C NMR spectroscopy. The electrical conductivity measurements of three of the four network polymers were unsuccessful; however chemical doping with NOBF 4 could be increased to a measurable value. The electrical conductivity of the dimeric phthalocyanines are in the semiconductor range.

“…Symmetrically tetra-and octa-substituted phthalocyanines (Pc) and naphthalocyanines (Nc) have been investigated intensively during the last few years with respect to their interesting physical properties which are used in the fields of e.g. semiconducting materials [3,4], non-linear optics, [5] laser dyes [6] and photodynamic cancer therapy [7]. However, in contrast to symmetrically substituted phthalocyanines reports on pure Pcs with lower symmetry have appeaad scarcely, mainly because of the problems associated with their separation.…”

Phthalocyanines and 2,3-naphthalocyanines are macrocyclic compounds which possess a variety of properties of potential importance in advanced technologies. The article discusses the influence of successive condensation of additional benzene rings to the phthalocyanine system. For this purpose three hexyloxy- and heptyl-substituted 2,3-dicyanonaphthalenes 3,7,11 and the respective 2,3-naphthalocyaninato nickel(II) complexes were prepared. In three statistical condensations of tetraphenylphthalodinitrile ( TPPN ) (12) and 2,3-dicyanonaphthalenes, 3,7,11, twelve unsymmetrical naphthobenzo-condensed porphyrazinato nickel(II) complexes 13b-15e were synthesized and separated by common column chromatography. All complexes were characterized by mass spectrometry, IR, UV and 1 H NMR spectroscopy.

“…The design of well-defined structures is based on the directional-bonding approach, using rigid ligands with highly directional coordinating groups and geometrically constrained metals entities. In this sense, the wheel-and-axle approach is being applied to obtain 1D polymers [7], which are also described as shish-kebab coordination polymers [8,9]. This type of linear supramolecules is formed when an ambidentate ligand bridges metalloporphyrins with hexacoordinated metals [10].…”

Bis-[methyl-1-hydroxy-1-cyclopentene-2-dithiocarboxylate-O,S]nickel(II) 1 was prepared starting from methyl 2-hydroxycyclopent-1-encarbodithioate ligand (CPDT) and Ni(II), and catena-[( 2 -4,4 -Bipyril)-bis-(methyl-2-hydroxy-1-cyclopentene-2-dithiocarboxylate-O,S)]nickel(ΙΙ) 2 was prepared in good yields from 1 plus 4,4 -bipyridyl (bpy) by shish-kebab methodology. The structure of 1 was confirmed by FTIR, elemental analysis, 1 H NMR, UV-vis in chloroform solution and in solid, XPS, and PXRD. Compound 2 was characterized by FTIR, elemental analysis, UV-vis in chloroform solution, and in solid, XPS, PXRD, ESR, and solid state magnetization measurements. The structure of the polymer was established mostly by PXRD, ESR, and magnetization.
