Induced by the two methyl 1H-NMR singulets observed for the dimethylquinquephenyl 1, several methyl-substituted quinquephenyl hydrocarbons have been studied concerning their conformational mobility and concerning their chiral properties: 1, 4 and 5 show coalescence of the methyl absorptions at higher temperature, whereas the methyl signals of 2 and 3 only consist of singulets at room temperature.The occurrence of diastereomers and enantiomers in quinquephenyls is discussed in view of the experimental observations.
