Synthesis of Highly Twisted and Fully pi-Conjugated Porphyrinic Oligomers
Highly twisted pi-conjugated molecules have been attractive but challenging targets. We report here an efficient synthesis of highly twisted diporphyrins with 126 degrees and 136 degrees twist angles that involves an oxidative fusion reaction of planar aminoporphyrin precursors at room temperature. Repeated amination-oxidative fusion sequences provide a unidirectionally twisted tetramer. The twisting angle of the tetramer is 298 degrees.
