چکیده

[reaction: see text] A new fluorescent probe N-butyl-4,5-di[2-(phenylamino)ethylamino]-1,8-naphthalimide 1 senses only Cu(II) among heavy and transition metal (HTM) ions by means of a colorimetric (primrose yellow to pink) method with a large red-shift in emission (green to red) attributed to the deprotonation of the secondary amines as a receptor conjugated to the naphthalimide fluorophore.

A red-shift colorimetric and fluorescent sensor for Cu2+ in aqueous solution: unsymmetrical 4,5-diaminonaphthalimide with N-H deprotonation induced by metal ions.

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...

Ratiometric sensing of fluoride and acetate anions based on a BODIPY-azaindole platform and its application to living cell imaging.

A new BODIPY-azaindole based fluorescent sensor 1 was designed and synthesized as a new colorimetric and ratiometric fluorescent chemosensor for fluoride. The binding and sensing abilities of sensor 1 towards various anions were studied by absorption, emission and (1)H NMR titration spectroscopies. The spectral responses of 1 to fluoride in acetonitrile-water were studied: an approximately 69 n...

Colorimetric sensing of Cu(II): Cu(II) induced deprotonation of an amide responsible for color changes.

9,10-Anthraquinone-based chemosensor 1 indicates the presence of Cu(II) ions among other transition metal ions with high selectivity by a color change from yellow to dark red. Chemosensor 2 shows binding toward Cu(II), Ni(II) and Co(II) with color changes from yellow to dark red, red and pale green, respectively. Especially, Co(II) binding with chemosensor 2 causes significantly green fluoresce...
