1′-carbamoylmethyl-8-nitrospiro[benzo[f]chromene3,2′-indole] derivatives, which underwent intramolecular cyclisation to derivatives of 3-nitro7a,15-methanonaphtho[1′,2′:6,7][1,3]oxazepino[3,2-a]indole upon treatment with a strong base. Laser excitation of the obtained uncoloured molecules of transand cis-3-nitro-7a,15-methanonaphtho[1′,2′:6,7][1,3]oxazepino[3,2-a]indole induced the formation of short-lived photogenerated
1-取代的9,9a-二氢-1H-咪唑并[1,2-a]吲哚-2(3H)-酮与2羟基-6-硝基-1-萘醛缩合得到1'-氨基甲酰基甲基-8-硝基螺[苯并[f]色烯3,2'-吲哚]衍生物,经过分子内环化生成3-硝基7a,15-甲烷萘并[1',2':6,7][1,3]氧氮杂[3,2-a]衍生物]吲哚用强碱处理。激光激发反式和顺式-3-硝基-7a,15-methanonaphtho[1',2':6,7][1,3]oxazepino[3,2-a]indole - 活的光生物种,它们在可见光谱中吸收并在纳秒时间尺度上热恢复到基态。
