Procedure

A 50 ml round-bottom flask, equipped with magnetic stirrer and nitrogen inlet, is charged with 0.50 g (0.19 mmol) of ferrocene acetic acid chloride (prepared in analogy to a process slightly modified from Macromolecules 26 (1993) 1936-1940), 10 ml of pyridine, 1.28 g (0.95 mmol) of brominated and, hydroxymethylated tetra(α-2,4-dimethyl-3-pentyloxy)-palladium-phthalocyanine and 12 mg (0.1 mmol) of 4-dimethylaminopyridine under argon, and the dark green solution is stirred for 20 hours at room temperature. The reaction mixture is then poured, with thorough stirring, on 100 ml of water and the precipitate is collected by filtration and washed with 4×50 ml of water. After drying the residue for 4 hours at 60° C. and 125 torr, it is dissolved in 15 ml of toluene and then 1.3 g of silica gel are added and the mixture is stirred for 10 minutes. The suspension is filtered and the residue is washed with 3×10 ml of toluene. Using a rotary evaporator, the filtrate is concentrated by evaporation to 4.8 g of a solution which is then poured, with stirring, on 49 ml of acetonitrile and stirred for 10 minutes. The precipitate is collected by filtration, washed with 3×50 ml of acetonitrile and dried overnight at 60° C. and 125 torr, yielding 1.2 g (80.5% of theory) of a green powder (brominated and hydroxymethylated tetra(α-2,4-dimethyl-3-pentyloxy)palladium-phthalocyanine which is esterified with ferrocene acetic acid) having the following analytical values: Elemental analysis: 12.71% Br, 4.49% Fe UV/VIS (NMP): λmax=723 nm, ε=148170 l·mol−1·cm−1 IR: C═O band for ester (cm−1) present TGA: point of inflection of the decomposition curve=278° C.
