Abstract

Measurements of the absorption, polarized fluorescence, and MCD of 1,6-methano[10]annulene, 1,6:8,13-bismethano[14]annulene, and 1,6:8,17:10,15-trismethano[18]annulene along with the semiempirical p-electron and AVE calcns. on these and related annulenes are reported. The transannular interaction in the methano-bridged annulenes is strong, and these homoarom. mols. can be viewed as examples of ...
