The synthesis of soluble titanium(IV) phthalocyanines, axially substituted with phenylenevinylenes (PVs) (R x PcTiX), is described. The reaction of peripherally tetra‐ and octasubstituted (phthalocyaninato)titanium oxides (R x PcTiO) 1 – 3 with chelating PV‐diols 4a – 4c leads to the formation of axially substituted R x PcTiX 5 – 7 . All compounds were characterized by IR, UV/Vis, MS, and 1 H NMR spectroscopy. Pcs 5 – 7 dissolved in dichloromethane are stable in the dark. The stability of solutions of 5 – 7 in sunlight depends on the nature of the peripheral substituents in the Pc ring and the chain length of the axial PV substituents.(© Wiley‐VCH Verlag GmbH & Co.
