Tetrabutylammonium fluoride induces the decomposition of 1-tert-butyl-4,4-dimethyl-5-(3-siloxyphenyl)-2,6,7-trioxabicyclo[3.2.0]heptane (4a) in DMSO to form an oxyanion of aromatic ketone (14a) as an emitter with high singlet-chemiexcitation yield comparable with that for a chemically initiated electron exchange luminescence (CIEEL) active dioxetane producing an oxyanion of aromatic ester as an emitter
四丁基氟化铵在DMSO中诱导1-叔丁基-4,4-二甲基-5-(3-甲硅烷氧基苯基)-2,6,7-三恶双环[3.2.0]庚烷(4a)分解形成芳族基团的氧阴离子作为发射体的酮(14a)具有高单线态化学激发产率,可与化学引发的电子交换发光(CIEEL)活性二氧杂环丁烷相比,产生芳香族酯的氧阴离子作为发射体。在类似的处理中发现了7-甲氧基萘-2-基类似物(4b)以迄今已知的CIEEL活性二氧杂环丁烷中最长的最大波长发射光。
