Series of linear tridentate PNPhPR‐ligands (R = Me, Et, Pln, Ph, Cp, Cy, iPr tBu) and molybdenum tricarbonyl complexes [Mo(CO)3PNPhPR] (R = Ph, Et, Cp, Cy, iPr) were synthesized and characterized using NMR‐, IR‐, and Raman spectroscopy as well as X‐ray crystallography. The influence of the different phosphine donor groups of the PNPhPR ligands on the bonding and activation of CO ligands is investigated. Importantly, all complexes are found to adopt a fac geometry, both in solution and in the solid state. This is in contrast to analogous complexes supported by PNHP ligands. DFT calculations reveal that the phenyl ring at the central amine function is the cause for the preferred geometry, hindering isomerization to a mer geometry.

“…Selective recognition of Cd 2 + ions was synthesized from 'turn-on' chemosensor azobenzene 67 ( Figure 65) which is attached to bis-quinoline unit. [95] The absorption spectrum of 67 appeared at 287 and 466 nm. In free-state and with excitation at 322 nm in the aqueous solution of acetonitrile (80 : 20, v/v CH 3 CN/H 2 O), chromophore 67 was attributed with weak fluorescence at 400 nm because of effective PET process.…”

Among various known hydroxyquinolines, 8-hydroxyquinoline (8-HQ) is the most prevalent moiety due to excellent property for the formation of the complex with different metal ions and anions, and utilized in a wide variety of applications in pharmacological and medicinal fields. 8-Hydroxyquinoline moiety and its analogues acts as fluorophoric ligands on complex formation with alkali and alkaline as well as transition metal ions and anions, thus, considered as an ideal building block in metallo-supramolecular chemistry for recognition, separation, and quantitative investigation of cations. 8-Hydroxyquinoline moiety is also used in various applications for the advancement of novel fluorescent chemosensors in a wide variety of areas viz., material chemistry, bioorganic chemistry, molecular imaging, analytical chemistry, molecular recognition, medical and biological science communities. The present review emphasises on the progress of sensing properties of 8-HQ centred small-molecule fluorescent chemosensors towards several metal ions viz.
