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.
本发明涉及新的单光子或双光子吸收荧光团,以及制备该荧光团的方法和利用该荧光团进行细胞成像的方法,更特别地,涉及具有比传统的双光子吸收荧光团acedan的荧光量子产率和双光子吸收截面值更高的新的双光子吸收荧光团,因此在
生物成像中有着广泛的应用前景。根据本发明的设计策略和化合物可实际用于开发新的D-π-A荧光团。
