Two series of [8]metacyclophanes with cis or trans configurated double bonds or triple bonds in the bridges were prepared; the first series 6, 8, and 10 contains phenylethynyl, the second series 13, 14, and 15 phenylethenyl substituents so that ππ interactions between the π centres in the bridge and the π centres of the basic chromophores tolan and trans-stilbene, respectively, can be studied.
