Abstract

2,3,6,7-Tetrasubstituted cis-anti-cis perhydroanthra-cenes and cis-decalines are suitable transducers for molecular signals via conformational transmission. Repeated use of a Lewis-acid catalyzed Diels-Alder reaction led to the stereoselective construction of the perhydroanthracene and decalin target molecules. A covalently induced triple ring flip of the perhydroanthacene system was achieved by the formation of a bisacetal. A chelation induced conformational switch was possible with bipyridine receptor groups in positions 6 and 7 and Zn(II) as the incoming signal. By attaching pyrene effectors in positions 2 and 3 the ability of the device to transduce a molecular signal from the receptor via the biconfor­mational transducer to the effector leading to an outcoming photosignal was proven.
