from 3,6‐dihydroxyphthalonitrile using triphenylphosphine dibromide as bromation reagent. Starting from 3,6‐dibromophthalonitrile, synthesis of 1,4,8,11,15,18,22,25‐octakis(4‐dodecylthiophen‐2‐yl)phthalocyaninatozinc(II) (ZnPc) was described. TGA demonstrated the perfect stability of ZnPc. The newly prepared ZnPc that was symmetricallysubstituted with thienyl substituents results in an intensively red‐shifted

The fundamental vibrational modes of a series of six halophthalonitriles have been studied using Raman and infrared spectroscopy. The vibrational assignment of experimental wave numbers obtained from solid samples was aided using quantum chemical computations. Semi-empirical methods and the local SVWN functional were used to obtain vibrational wave numbers and atomic displacement representations of the fundamental molecular vibrations. The study of a series of molecules with similar structure permits the identification of characteristic wave numbers and the effect of the halosubstitution in the molecular structure.
