摘要：

Through conformational studies on the topologically well-defined atropisomeric systems of organo-aluminium and -cobalt porphyrins, e.g. methyl[alpha(4)-5,10,15,20-tetrakis(2'-phenylphenyl)porphyrinato]aluminium (alpha(4)-1a), the presence of intramolecular CH-pi bonding interactions are indicated between alkyl groups bonded to the central metal atoms and aromatic rings located at the ortho position of the meso phenyl substituents upon proximal orientation.
