NMR study of dyadic and triadic splitting in copoly(arylene)phthalides based on diphenyl oxide and diphenyl sulfide

All 13C NMR signals of the poly(arylene) polymers, O‐1, S‐7, OS‐4, OOS‐3, OOOS‐2, SSO‐5, and SSSO‐6 (where O is a diphenyleneoxiphthalide unit and S is a diphenylenethiophthalide unit) in dyads and triads were assigned unequivocally with two‐dimensional NMR techniques (ge‐2D [1H–1H] COSY, ge‐2D [1H–...
