摘要: The present disclosure relates to Near-infrared fluorescent indicators for lysosomes and application thereof. These indicators are composed of lipophilic NIR BODIPY derivatives and ionizable bis-tertiary amine moiety, which enable the formation of a transient amphiphilic state in acidic environments specifically. This structural feature affords accurate lysosomal membrane targeting ability at nanomole staining concentration.

摘要: Provided are a novel aromatic amine derivative having a specific structure and an organic electroluminescence device in which an organic thin layer comprising a single layer or plural layers including a light emitting layer is interposed between a cathode and an anode, wherein at least one layer of the above organic thin layer contains the aromatic amine derivative described above in the form of a single component or a mixed component. Thus, the organic electroluminescence device is less liable to be crystallized in molecules, improved in a yield in producing the organic electroluminescence device and extended in a lifetime.
