Extremely large cavity assembled by self-interlocking of distorted biconcave porphyrins

X-Ray analyses of free base, zinc, and nickel complexes of 2,3;7,8;12,13;17,18-tetrakis(6,13-dihydro-6,13-pentaceno)-21H,23H-porphine revealed that the porphyrin chromophores adopted a heavily-saddled conformation by interlocking of the biconcave porphyrins in the crystals containing halobenzenes as crystalline solvents, while the ring was almost flat in the crystals obtained from benzene or from chlorobenzene and isopropanol.

STEREOCHEMISTRY OF SUBSTITUTED BICYCLOOCTENES

The epimerization of the methyl ester of 2,3,5,6-endo-bicyclo-7-octenetetracarboxylic acid produces three stereoisomers with one or two substituents in the exo position.Their structure was determined by 13C- and 1H-NMR spectroscopy and reactivity s
