Abstract Nitrogen doped Carbon Quantum Dots (NCQDs) is synthesized in most economical and easiest hydrothermal process. Here N-phenyl orthophenyldiamine citric acid are applied as a source of nitrogen carbon for the preparation NCQDs. The NCQDs were characterized using experimental techniques like UV−Vis absorption, FT-IR, transmission electron microscopy (TEM), X-ray Diffraction (XRD), dynamic light scattering (DLS), fluorimeter time resolved fluorescence spectroscopy. These quantum dots used to study their bactericidal activity against representative Gram-negative (E. coli P. aeruginosa) Gram-positive (B. Subtilis S. Aureus) bacterial strains by agar well diffusion method. Results shows that have maximum antibacterial against aureus with good inhibitory effect inhibition range from 2 mg mL-1 3 mL-1. also probe sensitive selective detection mercury. emission intensity has drastically quenched Hg2+ ion. Observed limit (LOD) 4.98 nM, much below than approved prescribed Environmental Protection Agency. Hence play an important role monitoring water quality. Measured yield ~ 53%. TEM image quasi-spherical shaped average size 3.5 nm.

Abstract Fluorescence sensors for complicated molecules such as pesticides were paid much attention lately due to the merits of simple operation, high sensitivity and selectivity, in‐situ detection. In this work, a novel fluorescent sensor pesticide starane was prepared based on imidazolium‐decorated bis‐cyanostilbene macrocycle ( IBM ). exhibited obvious “turn‐on” fluorescence change from dark blue‐green bright blue after sensing with selectivity among 28 kinds guests. The detecting limitation low 0.011 μM, which lowest one in literatures. mechanism confirmed that located cavity molecular interaction multiple hydrogen bonds, π‐π stacking hydrophobic interaction. application experiments suggested examined well test paper good quantitatively detected water samples, implying real‐time potential real environment daily life.
