Abstract:
Histidine-naphthalimide based receptors were prepared with
variation of the side chain amine having morpholine and 1,1-
dimethylethylenediamine. The prepared organic compounds
were then employed as a framework for the fabrication of
organic-inorganic nanohybrid assembly with the aim of
detection of environmentally essential anions in the aqueous
medium. The size and morphology of the nanohybrid particles
were confirmed with TEM and DLS analysis. Hybrid nanoparticles of morpholine naphthalimide show selective and
sensitive response with cyanide ion. Subsequently, the hybrid
nanoparticles of 1,1-dimethylethylenediamine naphthalimide
display visible difference with iodide ions and the response was
electrochemically detected. Both the hybrid nanoparticles were
utilized for the selective and sensitive detection of CN and I
ions; with quite low detection limit
