A novel indicator platform comprises a plurality of 1 H-lndol-3-yl indicator compounds that are capable of converting to a signalophore compound in response to an external stimulus. In one class of indicator compounds, the resulting signalophores are 2-benzylideneindoline compounds that are formed by an intermolecular Aldol-type process; in a further class of indicator compounds, the resulting signalophores are 10H-indolo[1,2-a]indole compounds that are formed by an intramolecular Aldol-type process. The indicators can be used in a wide array of applications relating, for example, to biological systems or optical data storage.
一种新颖的指示剂平台包括多种1H-
吲哚-3-基指示化合物,这些化合物能够在外部刺激作用下转化为信号体化合物。在一类指示化合物中,产生的信号体是通过分子间Aldol型过程形成的2-苄基亚甲基
吲哚化合物;在另一类指示化合物中,产生的信号体是通过分子内Aldol型过程形成的10H-
吲哚[1,2-a]
吲哚化合物。这些指示剂可用于涉及
生物系统或光学数据存储等各种应用中。
