In recent years, the development of methods to recognize and sense biologically and
environmentally important species has emerged as a significant target in the field of …

Selective anion sensors can be used in the colourimetric detection of certain anions. In the
present study, two new 1, 2, 4-triazole derivatives containing thiol group and azo moiety 3a …

The ubiquitous nature of anions has gained a bourgeoning interest among the
supramolecular chemists to develop artificial receptors for the selective recognition and …

Cyanide is potentially hazardous and quickly acting chemical used in many fields of
industry. Therefore, detection of cyanide is of main health concern due to its serious impacts …

The measurement of biologically relevant anions, such as fluoride, is an important task in
analytical chemistry, in particular, for dental health and osteoporosis. Although a large …

In this paper, we have design, synthesized and fully characterized a new meso-fluorescein
substituted one-walled calix [4] pyrrole (C4P7), obtained from simple and easily available …

Two novel fluorescein based dipyromethane probes DPM1 and DPM2 were constructed
from a simple and easily accessible fluorescein dye, and were fully characterized by means …

A novel vitamin B6 Schiff base analog (L) was synthesized by combining vitamin B6 cofactor
pyridoxal with 2-aminophenol. Receptor L displays a color change detectable by the naked …

In this study, three new compounds 6-substituted-3-acetylcoumarin 4-(2′-isocamphanyl)
thiosemicarbazones (3a, 3b, and 3c) were facilely synthesized and employed as colorimetric …

Abstract Two artificial colorimetric sensors, 4-[(E)-phenyldiazenyl]-2-[(E)-(phenylimino)
methyl] phenol and 2-{(E)-[(4-nitrophenyl) imino] methyl}-4-[(E)-phenyldiazenyl] phenol …
