Colorimetric and Ratiometric Fluorescent Chemosensor with a Large Red-Shift in Emission: Cu(II)-Only Sensing by Deprotonation of Secondary Amines as Receptor Conjugated to Naphthalimide Fluorophore
TL;DR: 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 method with a large red-shift in emission attributed to the deprotonation of the secondary amines as a receptor conjugated to the naphthalIMide fluorophore.

TL;DR: The location of the "spacer-receptor" unit in a 4-aminonaphthalimide fluorophore, which undergoes internal charge transfer in the excited state, is crucial for the suitability of the compound as a pH sensor as discussed by the authors.

Abstract: A number of substituted 1,8-naphthalimides and naphthalic anhydrides have been prepared and their absorption and fluorescence properties in absolute ethanol have been determined. In the absence of an alkylamino substituent in the naphthalene ring, the compounds are colourless and weakly fluorescent. In the presence of such a substituent they become yellow and frequently fluoresce strongly with quantum yields of the order of 0.8.
