Colorimetric detection of Cu(II) ion with a 1,3-bis-azachalcone derivative
2015, Sensors and Actuators, B: ChemicalCitation Excerpt :The naturally occurring chalcones, the biosynthetic precursor to many flavonoids, are known to perform various biological activities [9–11] along with their aza-derivatives which contain annular nitrogen atoms in phenyl ring. Such derivatives show large positive solvatochromic effect [12] due to existence of donor–acceptor assembly favouring an intra molecular charge transfer [13] and therefore of have drawn recent interest in their applications as materials in optical limiting [14], non-linear optical (NLO) [15], electrochemical sensing [16], Langmuir–Blodgett films [17] and photo-reactivity [18] assessment; apart from their utility as fluorogenic chemosensor for determination and quantification of water content in organic solvents [19] and saccharides estimation [20]. The azachalcone derivatives are also envisaged to form complexes with various metal ions due to existence of suitable coordinating sites in form of pyridyl and enones segments in their architecture although such complexes are not extensively known.
Spectral properties and micellization of 1-(2,5-Dimethyl-thiophen-3-yl)-3- (2,4,5-trimethoxy-phenyl)-propenone (DTTP) in different media
2013, Journal of LuminescenceCitation Excerpt :Solutes showing a charge transfer band often serve as reporter molecules of the surrounding environment. Donor–acceptor chalcone dyes form a class of compounds which are characterized by the above properties [2–6]. They have been applied in the food industry and photoreactive polymers [7].
