5,10,25,35,40-hexanornonapyrrin: the largest structurally characterized oligopyrrole prepared to date

摘要

The synthesis and X-ray diffraction-based characteriztion of a nonapyrrolic oligomer 2[5,5"-bis- ((2-(ethoxycarbonyl)-3,4,3',4',3",4"-hexamethyl-5,2':5',2"-terpyrrol-5"-yl)vinyl)-3,4,3',4',3",4"- hexamethyl-2,2':5',2"-terpyrrole] is reported. It was prepared by condensing (8) with 1 equiv of 3,4,3',4',3",4"-hexamethyl-2,2':5',2"-terpyrrole (9).
