N-Annulated perylene fused porphyrins 1 and 2 were synthesized by oxidative dehydrogenation using a Sc(OTf)3/DDQ
system. These newly synthesized hybrid molecules are highly soluble in
organic solvents and exhibit remarkably intense near-IR absorption, as
well as detectable photoluminescence quantum yields, all of which are
comparable to or even exceed those of either meso-β doubly linked porphyrin dimer/trimer or bis/tri-N-annulated rylenes.
