Analytical chemistry is now developing mainly in two areas: automation and the creation of
complexes that allow, on the one hand, for simultaneously analyzing a large number of …

Abstract Calix [4] arenes-based fluorescent chemosensors containing thiosemicarbazone as
a binding site and naphthalene as a fluorogenic unit in a 1, 3-alternate (L1) and cone (L2) …

Organophosphates are mainly used as pesticides to protect crops from pests. Because
organophosphate pesticides' use has expanded dramatically worldwide, accurate …

A newly synthesized calix [4] arene thiourea derivative decorated with 2‐(2‐aminophenyl)
benzothiazole unit is selected to take part important role in host‐guest interactions of the …

The physical nature of the noncovalent interactions involved in anion recognition was
investigated in the context of metalated calix [4] arene hosts, employing Kohn–Sham …

Heteroditopic calix [6] arenes are extensively exploited as synthetic receptors and as
molecular components of supramolecular threaded and interlocked structures. We describe …

We have developed a chemosensor using calix [4] arene, which features a
thiosemicarbazone binding/sensing unit and a naphthalene chromogenic group. Our …

Understanding the interactions of the calix [n] arene molecules with a variety of invited
chemicals entities is getting very important. In this context, we have studied a new host-guest …

Two new chromogenic sensors 1-(2-hydroxyphenyl)-3-(4-nitrophenyl) thiourea 1 and 1-(3-
hydroxypyridin-2-yl)-3-(4-nitrophenyl) thiourea 2 bearing nitrophenyl and thiourea groups …

We have synthesized and examined a series of calix [4] arene-based chemosensors
containing thiosemicarbazone or thiourea as a binding site and a pyridine-chromophore unit …
