Novel titanyl phthalocyanines titanyl-tetrakis-(1,1,4,4-tetramethyl-6,7-tetralino)-porphyrazine (1), titanyl- 2,3,9,10,16,17,23,24-octakis(phenylethynyl)-phthalocyanine (2a), titanyl-2,3,9,10,16,17,23,24-octakis((4-tert-butylphenyl) ethynyl)-phthalocyanine (3a), titanyl-(2,3,9,10,16,17,23,24-octakis(phenylethyl))phthalocyanine (2b) and titanyl-(2,3,9,10,16,17,23,24-octakis((4-tert-butylphenyl) ethyl)-phthalocyanine (3b) were prepared by reductive cyclotetramerisation of the respective dinitrile precursors in the presence of a titanium(IV) template. The spectroscopic properties were examined by UV-Vis and IR techniques. Soluble compounds 1, 2b and 3b were characterized by H-1 and C-13 NMR spectroscopy and show good stability towards thermal degradation. The molecular structure of 1 was determined, thus being one of the few examples of soluble phthalocyanines with a low grade of aggregation characterized by single crystal X-ray diffraction. Compound 1 crystallizes in the triclinic space group P (1) over bar, and the molecules arrange in a coplanar, slipped-stacked structure. (C) 2011 Elsevier B. V. All rights reserved.
