Chromotropic ferrocenyl chalcone with two pyrenyl groups: Solvatochromism and molecular chemosensor for Fe(III)/Fe(II) ions

Cyrhetrenyl chalcones: Synthesis, characterization and antimalarial evaluation

“…Considerable interest has been focused in their broad range of biological activities such as antibacterial [20], antitumour [21], antioxidant [22], antihyperglycemic [23] and anti-HIV [24]. Very recently, ferrocenyl chalcones have also been studied with regard to their nematocidal activities [25], fluorescent and electrochemical properties [26] as well as radicalscavenging capacities [27], molecular chemosensor activities [28] and as precursors for the syntheses of ferrocenyl pyrazolines [29,30]. Ferrocenyl chalcones have been conveniently prepared by a base-catalysed ClaiseneSchmidt condensation between acetylferrocene and an appropriately substituted aromatic aldehyde or ferrocene aldehyde and an appropriately substituted aromatic ketone.…”

A selective bis‐thiophene chalcone‐based spectrofluorimetric sensor for Fe3+

“…This emission property explores the field of chalcone-based fluorescent probes. There are many examples where chalcones have been used as metal ion sensors [23][24][25][26][27][28][29]; however, examples of Fe 3+ sensors are still scarce [30][31][32][33] owing to their ease of interfering with other transition metal ions [34][35][36][37]. Hence, designing a highly selective and sensitive sensor for iron is still challenging.…”

Fe3+-selective fluorescent probe based on aminoantipyrine in aqueous solution

“…There is an evidence indicated that either its overload or deficiency may induce many diseases, including dysfunction of organs and certain cancers [8,9]. Up to now, a serious of fluorescent sensors for Fe 3+ has been designed and synthesized [10][11][12][13][14][15]. But most of them were reported in organic solvent and the synthesis methods are always too complicated, which limit their application.…”
