A new bifunctional macrocyclic chelator featuring a conjugatable alkynyl-naphthalimide fluorophore pendant group has been prepared and its Gd(III) complex coupled to a cell-penetrating lipidated azido-Tat peptide derivative using Cu(I)-catalysed "click" chemistry. The resulting fluorescent conjugate is able to enter CAL-33 tongue squamous carcinoma cells, as revealed by confocal microscopy, pro...

In the title compound, C(21)H(22)N(2)O(4), the naphthalimide unit is almost planar (r.m.s. deviation = 0.081Å). The carboximide N atom and the five C atoms of the eth-oxy-carbonyl-methyl substituent also lie close to a common plane (r.m.s. deviation = 0.119Å), which subtends an angle of 71.06 (8)° to the naphthalamide plane. The piperidine ring adopts a chair conformation. In the crystal, inter...

A multiple switching fluorescent photochromic bisthienylethene bridged naphthalimide bearing cholesteryl groups was synthesized and its organogelator showed excellent photo-responsive and thermal reversible performance by light, thermal.

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 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.
