“…For compound 2 , the fluorescence emission centered at 405 nm was gradually strengthened and shifted to the long wavelength centered at 425 nm (Δλ = 20 nm) upon the addition of H 2 PO 4 − . Such a fluorescent enhancement could be rationalized on the basis of two possible signaling transduction mechanisms: (1) inhibition of PET and (2) binding‐induced rigidity of the host molecule . Before complexation with anions, there was PET from the thiodiazole to the anthracene unit, resulting in a weak emission.…”

Two new compounds (1 and 2) containing 2‐sulfydryl‐1,3,4‐thiodiazole have been synthesized and optimized. They both showed wide antibacterial activity for colon bacillus, Staphylococcus aureus, S. albus, dysentery bacillus and inferior activity for Bacillus subtilis. In addition, their binding properties were evaluated for biologically important anions (F–, Cl–, Br–, I–, AcO–, and H2PO4–) by theoretical investigation, UV–vis, fluorescence, and 1H NMR titration experiments, and they displayed strong binding ability for H2PO4– without the interference of other anions tested. Especially the binding ability of compound 2 containing anthracene with H2PO4– was 1000 times stronger than that of compound 1 containing nitrobenzene. Two compounds based on 2‐sulfydryl‐1,3,4‐thiodiazole have both properties of anion recognition and antibacterial activity.

“…The anion chemosensors synthesised and reported by several groups 208,[213][214][215][216][217][218][219][220][221][222] point towards hydrogen bonding interactions/deprotonation of acidic N-H with the added anions (F À , Cl À , Br À , I À , AcO À , H 2 PO 4 À , OH À ) that can be evidenced by a change in the absorption intensity and red shi of the absorption band in most of the cases producing a clear color change. The photophysical results of chemosensors 133-137 (Table 19) set a general trend of the processes involved in the recognition of the said anions.…”

“…Their coordination abilities are the result of the contribution of lone pairs of electrons on both nitrogen atoms in the characteristic shape of heterotricyclic systems. They have been found applications in supramolecular chemistry, luminescent sensors, and photosensitizers for solar cells [5,6,7,8,9,10,11,12,13,14,15]. 1,10-Phenanthrolines have also received much attention as potential targets for anticancer drug development [16,17,18,19,20,21].…”

New approaches to the synthesis of 4,7-dichloro-1,10-phenanthrolines and their corresponding 9H-carbazol-9-yl-, 10H-phenothiazin-10-yl- and pyrrolidin-1-yl derivatives were developed. Their properties have been characterized by a combination of several techniques: MS, HRMS, GC-MS, electronic absorption spectroscopy and multinuclear NMR in both solution and solid state including 15N CP/MAS NMR. The structures of 5-fluoro-2,9-dimethyl-4,7-di(pyrrolidin-1-yl)-1,10-phenanthroline (5d), 4,7-di(9H-carbazol-9-yl)-9-oxo-9,10-dihydro-1,10-phenanthroline-5-carbonitrile (6a) and 4,7-di(10H-phenothiazin-10-yl)-1,10-phenanthroline-5-carbonitrile (6b) were determined by single-crystal X-ray diffraction measurements. The nucleophilic substitutions of hydrogen followed by oxidation produced compounds 6a and 6b. The electrochemical properties of selected 1,10-phenanthrolines were investigated using cyclic voltammetry and compared with commercially available reference 1,10-phenanthrolin-5-amine (5l). The spatial distribution of frontier molecular orbitals of the selected compounds has been calculated by density functional theory (DFT). It was shown that potentials of reduction and oxidation were in consistence with the level of HOMO and LUMO energies.
