Synthesis and spectroscopic properties of chiral binaphthyl-linked subphthalocyanines†
Abstract
Chiral binaphthyl-linked subphthalocyanines (SubPcs) (1) have been prepared by the cyclotrimerization reaction of a phthalonitrile linked with (R)- and (S)-2,2′-binaphthyl in the presence of BCl3, and characterized by various spectroscopies including NMR, electronic absorption, CD, and MCD, as well as electrochemistry.
