Abstract The 1 H and 13 C nmr studies of 1,6‐dioxapyrene show the disruption of extended delocalization of the π electrons in this recently synthesized heterocyclic skeleton. A surprising coupling interaction through hydrogen bonding was detected in the precursors bearing formyl and hydroxyl groups in peri positions.
