Abstract:
The present invention relates to new one-photon or two-photon absorbing fluorophores, a method for preparing the same, and a method for cellular imaging using the same, and more particularly, to new two-photon absorbing fluorophores having higher fluorescence quantum yield and two-photon absorption cross-section value than those of the conventional two-photon absorbing fluorophore, acedan, and thus are promisingly applicable in bioimaging. The design strategy and the compounds according to the present invention may practically utilized for developing new D-π-A fluorophores.
Abstract:
Provided are acedan derivatives having an extended π bond, a method for preparing the acedan derivatives, and a method for two-photon microscopy imaging of amyloid-beta plaque using the acedan derivatives; more particularly, to two-photon absorbing fluorescent compounds having a longer absorption wavelength and emission wavelength than acedan and acedan derivatives which are conventional two-photon absorbing fluorophores. The compounds provided may be usefully used for in vivo imaging studies by imaging cells or tissue using the compounds, and may also be usefully used for diagnosing Alzheimer's disease by imaging amyloid-beta plaque using the compounds.
