Abstract

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.

摘要

N-稠合的苝酰亚胺卟啉 1 和 2 通过使用 Sc(OTf)(3)/DDQ 体系的氧化脱氢反应合成。这些新合成的杂化分子在有机溶剂中具有很高的溶解度，并表现出显著的近红外吸收，以及可检测的光致发光量子产率，所有这些都与中-β 双连接卟啉二聚体/三聚体或双/三-N-稠合的并苯相当，甚至超过它们。
