(BFB) suggest that the BAB- and DAB-sensitized reactions proceed by a preferential electron-transfer pathway within a triplet-exciplex intermediate, formed between the triplet-state sensitizer and the ground-state NT, to give N-phenyl-1-naphthalenecarboxamide (2) and p-toluic acid (3). On the other hand, the energy-transfer pathway in this exciplex intermediate, eventually forming 2 and 3, as well
标题羟胺 (NT, 1) 与 4,4'-双(二甲氨基)二苯甲酮 (BAB)、4-二甲氨基二苯甲酮 (DAB)、4,4'-二甲氧基二苯甲酮 ( DMB) 和 3,3'-双(三氟甲基)二苯甲酮 (BFB) 表明 BAB 和 DAB 敏化反应通过在三重态敏化剂和基态 NT,得到 N-苯基-1-萘甲酰胺 (2) 和对甲苯甲酸 (3)。另一方面,这种激基复合物中间体中的能量转移途径,最终形成 2 和 3,以及甲苯 (4),在 DMB 和 BFB 敏化的反应中占主导地位,比 BAB 的二甲氨基具有更少的给电子取代基和民建联。
