Two series of unsymetrically functionalized, carboxyethynylphenyl‐containing porphyrins, bearing either 2,4,6‐triisopropylphenyl or triphenylamino substituents at three of the four meso positions, have been prepared by Sonogashira coupling from the corresponding ethynyl‐ or iodo‐functionalized porphyrin precursors. UV/Vis and electrochemical measurements have been performed to determine the electronic features of these new compounds and, hence, their potential as dyes for dye‐sensitized solar cells.
