New Selective Synthesis of Substituted Tetrabenzoporphyrins

摘要

Porphyrins with an extended pi-system,represented by tetrabenzoporphyrins (TBPs)as the simplest examples,possess a set of unique properties.This accounts or the extensive practical application of these compounds,for example,in photodynamic therapy [1],in nonlinear optics [2],and as organic semiconductors [3].In terms of their optical characteristics,meso-tetra-aryltetrabenzoporphyrins Ar_4TBPs were shown to be ecellent phosphorescent sensors of oxygen [4],suitable,in particular,for in vivo mesurments [5].
