ChemInform Abstract: Synthesis and Characterization of Metal-Free and Metal Derivatives of a Novel Soluble Crown-Ether-Containing Phthalocyanine.

The synthesis and characterization of novel metal-free and metallophthalocyanines, fused symmetrically in non-peripheral positions with four octaoxamacrocycle has been synthesized by cyclotetramerization of the 2,5,8,11,14,20,23,26,29,32-decaoxatricyclo [31.2.2.115,19]octatriconta-1(36),15,17,19(38),33(37),34-hexaene-34,35-dicarbonitrile (5) which was prepared by the reaction of 3,6-bis[2-(2-{2-[2-(toluene-4-sulphonyl)-ethoxy]-ethoxy}-ethoxy)-ethoxy]-phthalonitrile (3) and 1,3-dihydroxybenzene (4). The novel compounds were characterized by using elemental analysis, 1 H , 13 C NMR, IR, UV-vis and MS spectral data.

New metal-free 5 and metallophthalocyanines 6-11( M = Cu , Ni , Co , Pb , Zn ) fused in peripheral positions with four 24-membered tetraoxatetraaza macrocycles were prepared by cyclotetramerization of 24,25-dicyano-4,10,13,17-tetra(toluene-p-sulfonyl)-1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22-didicontinehydrobenzo[y][3,9,12,18]tetraaza[1,7,16,22]tetraoxatetradicontine in the presence of the corresponding metal salt or a strong organic base. While the N-tosylated derivatives of the phthalocyanines are soluble in common organic solvents, the detosylated derivative of copper phthalocyaninate is soluble in water. The aggregation properties of the phthalocyanines were also investigated as a function of concentration, solvent and oxidative medium. The new compounds are characterized by a combination of elemental analysis and 1 H NMR, 13 C NMR, IR, UV-vis and MS spectral data.

An original method based on metal-free ligand and lanthanide acetate direct interaction in the presence of a strong organic base (DBU) is used to prepare sandwich-type gadolinium and ytterbium crown-ether substituted phthalocyanines bis[4,5,4′,5′,4″,5″,4‴,5‴-tetrakis(1,4,7,10,13-pentaoxatridecamethylene)phthalocyaninato]gadolinium (ytterbium) and tris[4,5,4′,5′,4″,5″,4‴-,5‴-tetrakis(1,4,7,10,13-pentaoxatridecamethylene)phthalocyaninato]digadolinium (ytterbium) which are characterized by MALDI-TOF mass spectrometry and UV-vis spectroscopy.
