title: Axially chiral directly beta,beta-linked bisporphyrins: synthesis and stereostructure.
abstract: [reaction: see text] A novel type of "superbiaryl", the first porphyrin dimers with an intrinsically chiral structure, has been prepared. The atropo-enantiomers were configurationally assigned by HPLC-CD combined with quantum chemical CD calculations.
