| Abstract: | 3,6‐Dibromophthalonitrile was successfully synthesized 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 symmetrically substituted with thienyl substituents results in an intensively red‐shifted Q‐band. The HOMO and LUMO values of ZnPc were acquired by CV. |
