A fluorescent chemosensor based on naphthol for detection of Zn(2)

Luminescence. 2016 Feb;31(1):236-40. doi: 10.1002/bio.2951. Epub 2015 May 29.

Abstract

A simple naphthol-based fluorescent receptor 1 was prepared and evaluated for its fluorescence response to heavy metal ions. Receptor 1 exhibits an 'off-on-type' mode with high selectivity in the presence of Zn(2+) ion. The selectivity of 1 for Zn(2+) is the consequence of combined effects of chelation-enhanced fluorescence (CHEF), C = N isomerization and π-π stacking interaction between the two naphthalene rings.

Keywords: Schiff base; chemosensor; fluorescence; turn-on.
