Abstract


Newly synthesized indolyl(thienyl)maleimides containing naphthalimide linkers were found to exhibit weak fluorescence due to PET effect. Irradiation at 436 nm wavelength led to the formation of their cyclic isomers. The obtained compounds showed the properties of chromogenic and fluorogenic  chemosensors for F– ions.
