| Abstract: | Application of the synthetic methodology developed in our laboratory yields molecular clips and tweezers with corannulene pincers and cyclooctadiene or cyclooctatetraene tethers. These highly nonplanar systems possess a potential for binding guest molecules of various sizes. One of the clips, bis(benzocorannulene)a,e]cyclooctadiene, exists in a ‘open’ chair conformation encapsulating solvating nitrobenzene in the solid state, while it is expected to prefer an internally π-π stacked twist-boat conformation in the gas phase. |
