Abstract:Porphyrins that bear halogens at the meso‐aryl positions are useful building blocks for the preparation of light‐harvesting arrays and materials through cross‐coupling procedures. Despite the wide use of such intermediates, their scale‐up and purification are usually hampered by tedious chromatographic separations because of the statistical nature of the synthetic protocol and the similar polarity of the different products. Here, we propose the use of porphyrins bearing a triflatophenyl group as alternative st… Show more
