Abstract
Ten meso-tetraphenylporphyrin-type heterodimers containing a partly or completely β-brominated subunit were synthesized and characterized by UV-visible spectroscopy, cyclic voltammetry and spectroelectrochemistry, showing the presence of low electronic interactions between the two subunits. The investigated compounds are represented as M[(tripp-tpp(Br4)]M and M[tripp-tpp(Br8)]M (M = 2H, Zn, Ni, Co and Cu) where tripp-tpp(Br4) is the tetraanion of 1-[5-(10,15,20-triphenylporphyrinyl)]-4-[10-(2,3,12,13-tetrabromoporphyrinyl)] -benzene and tripp-tpp(Br8) is the tetraanion of 1-[5-(10,15,20-triphenylporphyrinyl)]-4-[10-(2,3,7,8,12,13,17, 18-octabromoporphyrinyl)]-benzene. One of the synthesized dimers, H 2[tripp-tpp(Br8)]H2, was characterized by a single-crystal X-ray investigation.
