A novel indicator platform comprises a plurality of 1H-Indol-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.
一种新型指示剂平台由多种 1H-
吲哚-3-基指示剂化合物组成,这些化合物能够在外部刺激下转化为信号团化合物。在一类指示剂化合物中,产生的信号团是通过分子间醛醇型过程形成的 2-亚
苄基吲哚啉化合物;在另一类指示剂化合物中,产生的信号团是通过分子内醛醇型过程形成的 10H-
吲哚并[1,2-a]
吲哚化合物。这些指示剂可广泛应用于
生物系统或光学数据存储等领域。
