A novel 4-amino-1,8-naphthalimide (NDI) with two different metal cation receptors connected at 4-amino or imide nitrogen positions respectively was designed and prepared. Significant internal charge transfer (ICT) as well as photoinduced electron transfer (PET) from the receptors to NDI is revealed by the shifted UV-vis absorption spectra and significant fluorescence quenching. Both Zn(2+) and ...

A naphthalimide appended rhodamine based fluorescent chemosensor '1' is synthesized which undergoes through bond energy transfer in the presence of Hg(2+) ions in mixed aqueous media.

A selective fluorescent chemodosimeter for mercury ion based on the mercury-promoted intramolecular cyclic guanylation of thiourea connected on 1, 8-naphthalimide is described.

A fluorescent probe was designed and shown to detect Cu2+ ratiometrically and selectively in aqueous solutions based on naphthalimide excimer-monomer switching.

Cations and anions are indispensable resources for the development of nature modern industry agriculture, exploring more efficient technology to monitor them is urgently needed. A multifunctional fluorescent probe based on 1,8-naphthalimide, N-(2-thiophenhydrazide)acetyl-4-morpholine-1,8-naphthalimide (TMN), was successfully designed synthesized detection Co2+, F−, CN−, with N-carboxymethyl-4-m...

This article deals with three cellulose-based fluorescent macromolecular sensors by introducing 1,8-naphthalimide fluorophore to cellulose. First, through the etherification reaction of cellulose BrCH2CH2NH2, –NH2 group–bearing CS 1 was obtained. Then, group reacts 4-bromo-1,8-naphthalic anhydride synthesize a naphthalimide derivative (CS 2). Finally, recognition introduced substituting Br atom...

Correction for 'Glycosylation enhances the aqueous sensitivity and lowers the cytotoxicity of a naphthalimide zinc ion fluorescence probe' by Lei Dong et al., Chem. Commun., 2015, DOI: 10.1039/c5cc04357c.

A new cleft-shaped 2-picolyl-4-amino-1,8-naphthalimide Tröger's base ( TBNap ) was synthesized and employed as a fluorescent ‘turn-on’ chemosensor for the discriminative sensing of volatile halogenated solvents.

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.
