What Is Design?

Abstract

A series of meso-β bridged extended porphyrins substituted with long aliphatic chains were synthesized and fully characterized. Two different synthetic strategies were tested to obtain the target structures. The synthetic steps were optimized in order to obtain scalable routes for the production of sufficient quantities of π-extended porphyrins for material science studies. The porphyrins were obtained either as free bases or complexed with Ni II or Cu II . UV-Vis spectroscopy and polarized light microscopy was used for the analysis of the material properties of the π-extended porphyrins. The results obtained with our compounds are not compatible with the results reported in the literature.
