Synthesis and spectral properties of 4-amino- and 4-acetylamino-N-arylnaphthalimides containing electron-donating groups in the N-aryl substituent

Abstract: A method for the synthesis of N aryl substituted 4 amino and 4 acetylaminonaphthalimide derivatives with mono and dialkoxy groups or a 15 crown 5 moiety in the N aryl substituent is described. The introduction of electron donating alkoxy groups into the benzene ring of the N aryl fragment results in fluorescence quenching of the naphthalimide chromophore, which is most pronounced in the spectra of N acetyl derivatives. The photophysical properties of the synthesized 4 amino and 4 acetylaminonaphthalimides depe… Show more

“…It was shown also that the presence of crown ether group in the N-aryl moiety of naphthalimide leads to dramatic decrease of emission intensity with respect to crown free N-phenylnaphthalimide due to efficient electron transfer between naphthalimide chromophore and receptor unit. [23,24] Upon the addition of metal ions the lone pair of electrons of crown ether receptor's heteroatoms are engaged in cation binding, this suppresses PET process and causes fluorescence enhancement (Scheme 5).…”

“…[14,16,28] Как известно, главным условием безызлуча-тельного переноса энергии по механизму Фёрстера от донора, находящегося в возбужденном состоянии, на акцептор через диполь-дипольное взаимодействие между молекулами является необходимость перекры-вания спектров испускания донора (DС) и поглощения Energy Transfer in Planar Systems Based on Naphthalimide Derivatives акцептора (A). Из данных, представленных на Рисунке 4 видно, что спектр испускания донорного флуорофора (алкилированныйазадитиакраун-замещенный 4-(ацил)-амино-нафталимид) хорошо перекрывается со спек-тром поглощения второго соединения (алкилированный 4-амино-нафталимид).…”
