“…Thus, 6 j could serve as a detector for Hg 2 + , Fe 3 + , and Cu 2 + ions, without requiring instrumentation or intricate operating procedures. [33][34][35] The interactions of the 5 g and 6 j probes were investigated using UV/Vis absorption titration (Figures 2 and 3). The gradual addition of the metal ions (Hg 2 + , Fe 3 + , and Cu 2 + ) up to a maximum concentration of 10 mm significantly increased the absorption are strongly attracted to the terpyridine moiety of the probes, [35,36] intensities of the probes.…”

An environment-friendly synthetic protocol was developed to access polyfunctionalized bipyridines from readily available amines, chromone-3-carboxaldehydes, and pyridinylacetonitriles under catalyst-and additive-free conditions using the biorenewable neoteric solvent dihydrolevoglucosenone (Cyrene™). In this strategy, amines served as both a mild-base promoter and a substrate. In addition, water was the only by-product of this reaction. This multi-component protocol provided highly diverse 2,3-, 3,3-, and 3,4-bipyridines in good-to-excellent yields. Operational simplicity, short reaction time, excellent atom economy, and easily obtainable substrates are among the features of this microwave-assisted synthesis. Additionally, the compounds synthesized via this method have demonstrated the ability to detect heavy metals, specifically mercury(II), copper(II), and iron (III) ions.

“…37 In 2015, Mohandoss synthesized β-CD:1,5-DHAQ as a new dual functional probe with high selectivity and sensitivity to Fe 3+ . 38 Alternatively, Ferreiro studied two types of the proton transfer reaction mechanism of 1,5-DHAQ, based the fact that the dual proton transfer reaction induced the tautomer with high instability, using the Hartree− Fock ab initio method. 39 Furthermore, from the point view of molecular orbital theory, the intramolecular hydrogen bonding influence on molecular structure, electronic spectra, and thermodynamical function of anthraquinone and its hydroxyl derivatives were also investigated by adopting density functional theory (DFT) method.…”

The single and dual cooperated proton transfer dynamic process in the excited state of 1,5-dihydroxyanthraquinone (1,5-DHAQ) was theoretically investigated, taking solvent effects (ethanol) into account. The absorption and fluorescence spectra were simulated, and dual fluorescence exhibited, which is consistent with previous experiments. Analysis of the calculated IR and Raman vibration spectra reveals that the intramolecular hydrogen bonding interactions (O20–H21···O24 and O22–H23···O25) are strengthened following the excited proton transfer process. Finally, by constructing the potential energy surfaces of the ground state, first excited singlet state, and triplet state, the mechanism of the intramolecular proton transfer of 1,5-DHAQ can be revealed.
