Morpholine-substituted 1,8-naphthalimide fluorophores exhibit solvent and pH-dependent emission characteristics based on aggregation, form robust chemically reversible metallogels.

A new organic dye (FD-9) derived from 1,8-naphthalimide is synthesized and shows significant aggregation induced emission (AIE) characteristics. The FD-9 dye presents excellent photostability and low toxicity, which can specifically track a cell membrane for 4 days.

A new polymerizable fluorescent sensor based on the photoinduced electron transfer PET for the selective determination of fluoride ions in DMF solutions has been synthesized. The sensing system was prepared by incorporating 4-Amino-1,8-naphthalimide derivatives containing thiourea side chain at the amino moiety AFTN as a neutral F- selective flourophore and was characterized by use of the DSC, ...

A series of novel mono- and di-substituted N-n-butyl-1,8-naphthalimide derivatives were synthesized simultaneously via a three-step reaction. The single crystal structure of N-n-butyl-4-[N',N'-bis(2',4'-dichlorobenzoyl)ethylamino]-1,8-naphthalimide (3f) was determined. The UV-vis and fluorescence properties of compound 3f were investigated. The 3f showed highly selective and sensitive fluoresce...

A family of structurally related LOX enzymes present in human cells which catalyse the metabolism of released arachidonic acid from phospholipids by inflammatory stimuli, to biologically active mediators. Mainly, expression of three types of LOXs occurs in cells, which catalyse the insertion of molecular oxygen into the molecule of arachidonic acid at carbon 5, 12, and 15. According to this che...

4,5-Diamino-1,8-naphthalimide (DNP)-based chemosensor was designed and synthesized. Probe specifically recognized Cu(2+) ions in neutral aqueous solution. The capture of Cu(2+) by the receptor resulted in deprotonation of the secondary amine conjugated to the 1,8-naphthalimide chromophore, so that the electron-donation ability of the "N" atom would be greatly enhanced; thus probe showed a 50 nm...

This critical review focuses on the development of anion sensors, being either fluorescent and/or colorimetric, based on the use of the 1,8-naphthalimide structure; a highly versatile building unit that absorbs and emits at long wavelengths. The review commences with a short description of the most commonly used design principles employed in chemosensors, followed by a discussion on the photoph...

Taking advantage of the fluorescence property of alkyne-modified naphthalimide, the two-photon excited fluorogenic probe Naph-yne is used for azide-tagged mannosyl glycoprotein imaging both at the cellular level and for vertebrate model organisms.
