## Abstract This work describes the synthesis and characterisation by electronic absorption spectroscopy, cyclic voltammetry and by a solvatochromic investigation of __meso__‐tetraphenylporphyrins and their Zn^II^ complexes substituted at the β pyrrolic position by a pseudo‐linear, π‐delocalised or
