Witryna27 lut 2024 · The naphthalimide fluorophore has the advantage of easily tunable photophysical properties by blocking and/or unblocking the internal charge transfer (ICT) process. It is highly photostable, resistant to pH interference, and possesses a large two-photon absorption cross-section. Importantly, 1,8-naphthalimide can be easily … WitrynaNaphthalimide, as a classical fluorophore, has high fluorescence quantum yield, and the imide bond has strong electron absorption ability. Its fluorescence spectrum can be adjusted by changing the substituent group at C4 or C5, and its structural modification is relatively simple. In addition, naphthalimide has a two-photon fluorescence ...
