Notizen: Abstract Low energy singlet and triplet states for a series of [2 n ]cyclophanes are discussed in terms of the results of a simple model calculation. Experimental trends can be explained under the assumption of significant σ-π interaction involving the saturated bridges. This interaction destabilizes low energy “excimer” states, in contrast to the usual red shift observed for alkylbenzenes. The observed near-constancy of the onset of the absorption spectra can be explained by near-cancelation of through-bond and through-space contributions.
