Abstract

Syntheses of [2.2](3,11)dibenzo[c,l]chrysenophane, [2.2](4,4′)-biphenylo(3,11)dibenzo[c,l]chrysenophane, and [2.2](4,4′)biphenylo-(3,11)dibenzo[c,l]chrysenophadiene are described. The unusually strained structures were supported by their 1H-NMR spectra, electronic spectra, and X-ray crystallographic analyses.
