Graphical Abstract
  • ], and crosslinked polymers [14][15][16][17]. Since crosslinking polymers requires high reaction efficiency under mild conditions, developing such reactions is crucial. We previously reported the regioselective double azide addition to octadehydrodibenzo[12]annulene with hexyloxy substituents (DBA-OHex
  • , DBAs substituted with electron-withdrawing groups have been little studied [19], and their chemical stability and physical properties are not well understood. In this paper, a new DBA substituted with ester groups was synthesized, and the double azide addition was comprehensively investigated. Finally
  • , the double azide addition reaction was applied to polymer crosslinking and the mechanical properties of the self-standing polymer films were compared.
