| Research Abstract |
We designed rigid cyclic compounds consisting of anthracene units and acetylene (or diacetylene) linkers as new π-conjugated compounds. Substituents were introduced at inner congested positions, and we isolated some novel stereoisomers (diastereomers and enantiomers) based on the steric hindrance between the ring framework and the intraannular substituents. The structures and dynamic behavior of these isomers were investigated by X-ray analysis, NMR spectra, and DFT calculations. We propose a new concept of stereochemistry through this molecular design.
