How paramagnetic and diamagnetic LMOCs detect picric acid from surface water and the intracellular environment: A combined experimental and DFT-D3 study

Diamagnetic and Paramagnetic Luminescent Metal Organic Complexes (LMOCs) have been reported for Explosive and Pollutant Nitro Aromatic (epNAC) recognition. The diamagnetic complex shows a highly intense AIE induced by NEt3H+, which disappears after picric acid recognition and subsequently RET will quench the emission intensity. Radical stabilized paramagnetic LMOCs seem to be active but show lower sensing efficiency in comparison with diamagnetic LMOCs. Solution and solid state spectroscopy studies along with DFT-D3 have been executed to enlighten the host guest interaction. Limit of PA detection is ～250 ppb with a binding constant of 1.2 × 105 M-1. Time-stepping, i.e. intervening in the problem of picric acid recognition from surface water collected from several places of West Bengal, India, has been performed. Mutagenic picric acid has been successfully detected in an aqueous medium inside both prokaryotic and eukaryotic cells at a ppm level using fluorescence microscopy.

Single sensor for multiple analytes in different optical channel: Applying for multi-ion response modulation

A Schiff-base, (2,4-di-tert-butyl-6-((2-hydroxyphenyl-imino)-methyl)phenol) (L), has been improved to function as a simultaneous multi-ion probe in different optical channel. The probe changes from colorless to orangish upon being deprotonated by F?, while the presence of Al3+ significantly enhances the fluorescence of the probe due to the inhibition of C[dbnd]N isomerization, cation-induced inhibition of excited-state intramolecular proton transfer (ESIPT), and chelation enhanced fluorescence (CHEF). Dual-channel “off-on” switching behavior resulted from the sequential input of F? and Al3+, reflecting the balance of independent reactions of Al3+ and F? with L and with one another. This sensing phenomenon realizes transformation between multiple states and beautifully mimics a “Write-Read-Erase-Read” logic circuit with two feedback loops.

Spectroscopic studies on bis(3,5-di-t-butyl-1,2-benzoquinone 1-oximato)copper(II) and its mixed-ligand complexes. Copper(II)-radical ferromagnetic coupling

Bis(3,5-di-t-butyl-1,2-benzoquinone 1-oximato)copper(II), Cu(ox)2, and its mixed-ligand complexes, Cu(ox)Lx [Lx = 8-hydroxyquinolinato (L1), N-Phenyl-salicylaldimine (L2), N-phenyl-3,5-di-t-butylsalicylaldiminato (L3) and N-(2-hydroxyphenyl)-3,5-di-t-butylsalicylaldiminato (L4)], were prepared and their spectral behavior as well as redox-reactivity towards PPh3, (m-ClC6H4)3P, (m-CH3C6H4)3P and PPh2-(CH2)4-PPh2 studied by analytical and spectroscopic (IR, UV-vis, ESR) techniques and magnetic measurements. Cu(ox)2 and Cu(ox)L4 complexes prepared in air show μef values of 2.84 and 3.33 μB, respectively, and are consistent with an S = 1 and S = 3/2 ground states. Both compounds are formulated as copper(II)-radical complex exhibiting intramolecular ferromagnetic coupling between the orthogonal dx2-y2 magnetic orbital of the CuII ion and that of the π-radical ligand.

Aluminum complexes containing salicylbenzoxazole ligands and their application in the ring-opening polymerization of: Rac -lactide and ?-caprolactone

Two series of four-coordinate aluminum (1a-9a) and five-coordinate aluminum (1b-9b) complexes were successfully synthesized via the reactions between the corresponding salicylbenzoxazole ligands and 1 or 0.5 equivalents of AlMe3, respectively. The synthesized aluminum complexes were characterized by 1H and 13C NMR spectroscopy and elemental analysis. The solid-state structures of complexes 7a and 1b were determined using single crystal X-ray diffraction. Upon addition of 1 equivalent of benzyl alcohol, all complexes were efficient initiators for the ring-opening polymerization (ROP) of rac-lactide (rac-LA) and ?-caprolactone (?-CL). The polymerizations were living with a good control over molecular weights and molecular weight distributions. Under immortal polymerization conditions, all four-coordinate aluminum complexes (1b-9b) exhibited a living polymerization with the obtained molecular weights proportional to the ratio of monomer/benzyl alcohol and the PDIs were narrow. Kinetic studies revealed that both rac-LA and ?-CL polymerizations mediated by all complexes were first-order in monomers. The effects of ligand structure and coordination geometry on the catalytic activity and stereoselectivity were discussed. A good isoselectivity control was achieved for the polymerizations mediated by complexes 4b (Pm = 0.75), 5b (Pm = 0.74), and 9b (Pm = 0.74).

Synthesis, X-ray structure and spectroscopic studies of Mo(O)2(3,5-di-tert-Busap)(EtOH)

A new six-co-ordinate cis-dioxomolybdenum(VI) complex [Mo(O)2(3,5-di-tert-Busap) (EtOH)], (where 3,5-di-tert-Busap2- = the Schiff base dianion 3,5-di-tert-butyl-N-salicylidene-2-aminophenolate), has been prepared. The complex is characterised by IR, 1H and 13C NMR and UV/vis spectroscopy and is stable to air, but above 413 K or in non-coordinating solvents loses an ethanol molecule, forming an dimeric compound with an unsymmetrical dioxygen bridge as indicated by IR spectroscopy.
