The triptycene skeleton has been used to measure (1,5) interactions between aldehyde groups, placed at both sp3 centres, and hydroxy or methoxy groups, placed at the respective ortho position on a benzene ring; HO...CHO interactions of 2.621-2.624 A and MeO...CHO interactions of 2.528-2.584 A were observed with the O...C vector making angles of 105.3-133.7° with the carbonyl bond. The lack of a competing conjugation with the framework for the electrophilic group is a favourable factor compared to the use of peri-naphthalene systems. This journal is The Royal Society of Chemistry.
