Two new fluorescent sensors C1 and C2 with 4-aminoantipyrine unit have been prepared
and characterized. Their complexation behaviour and binding mode towards Al 3+ and other …

The specific colorimetric detection of Cu2+ in the context of interference from coexisting
metal ions in aqueous solution is a challenge. Therefore, a series of Cu2+ colorimetric …

A new symmetrical truxene derivative (TP3) containing three dipicolylamino peripheral
groups is successfully synthesized in four synthetic steps with an overall yield of 42%. This …

Copper (II) ion chemical sensors based on pyridine-thiourea derivatives; N-pyridyl-N'-
(biphenyl-4-carbonyl) thiourea (L1), and N-pyridyl-N'-(3, 5-dimethyoxybenzoyl) thiourea (L2) …

New calix [4] arene derivatives with oxalylamido loops on their upper and lower rim (7, 8)
have been designed and synthesized. It has been determined that molecular receptor 8 is …

This work has the goal of developing and evaluating a reusable fluorescent nanosensor for
detection of Cu (II) ion in aqueous solution, based on the immobilization of rhodamine B in …

Calcein was first covalently grafted onto the surface of magnetic silica nanoparticles to
obtain a novel fluorescent nanoprobe for sensitive and selective determination of Cu (II) ion …

Although the development of sensors for the detection of Cu2+ ions has significant
importance, sensitive and selective recognition systems are still limited. Herein, the non …
