A new ferrocene–anthracene dyad for dual-signaling sensing of Cu(II) and Hg(II)

Designing a ferrocene biphenyl pyridine modified electrode for the non-enzymatic electrochemical detection of catechol

“…23 In this study, Fc (COOH) 2 -AuNPs-GCE shows the highest peak current of 15.9 mA at 0.48 V. Later, Jin-Zhu Ge et al detected mercury and copper using anthracene appended Fc unit conjugated with thiourea and aniline group for dual responsive detection by spectroscopic and electrochemical technique. 24 Here, the operating potential was found to be high at 0.37 V and the limit of detection was 3.0 Â 10 À6 M and 1.9 Â 10 À6 M, respectively, for mercury and copper.…”

Strategic design of a 2,6-disubstituted pyridine-based probe having hard-soft centers: responsive divergence from one core

“…8,25,36,37 Moreover, as far as the soft centre as a binding unit for Hg 2+ ions is concerned, our probe has comparable LOD. 38–41 The Cu 2+ complexes with both 5 and 7 are formed by hard–hard binding, and hence are expected to be stronger than the soft–soft complexation formed by Hg 2+ ions with 7 . The stability and sensitivity of 5 and 7 towards Cu 2+ ions are almost similar or comparable as per their stability constants and LOD values.…”

Photophysical Properties of Anthracene Derivatives

“…Ge at al. [129] synthe- These competing reactions were mainly attributed to electron transfer from the amine to the exited state of anthracene, and the intermediate was the exciplex formed in the excided state between these two compounds [122,123]. In addition to their interesting properties in photoluminescence, exciplexes are known as well to be the "obligatory" [124] intermediate of a photochemical reaction like in the [2 + 2] cycloaddition of 9cyanophenanthrene 61 with β-methylstyrene 62 (Scheme 10).…”

“…Ge at al. [129] synthesized the anthracene-appended ferrocene dyad 64 containing the aniline and thiourea donor moieties for sensing Cu(II) and Hg(II) ions (Figure 55). Dyad 64 exhibited a very weak emission at λ max = 395, 416, and 440 nm, respectively.…”
