A simple synthetic method of [3.3]cyclophanes <I>via</I> dithia[4.4]cyclophanes is presented. The spectra of a variety of cyclophanes were examined and compared to those of [2.2]analogues. It was concluded from the absorption spectra that the transannular π-π interactions of the cyclophanes were strongly dependent on both ring-to-ring distance and overlapping mode. From the emission spectra, it was described that cyclophanes of parallel sandwich type formed easily normal excimers, whereas [2.2]metacyclophane and [2.2]- and [3.3]metaparacyclo-phanes formed strained excimers showing marked red shifts of fluorescence bands.
