Impact of tunable 2-(1-indol-3-yl)acetonitrile based fluorophores towards optical, thermal and electroluminescence properties.

Herein, we have synthesized 4,5-diphenyl-1-imidazole and 2-(1-indol-3-yl)acetonitrile based donor-π-acceptor fluorophores and studied their optical, thermal, electroluminescence properties. Both the fluorophores exhibit high fluorescence quantum yield ( = <0.6) and good thermal stability ( = <300 °C), and could be excellent candidates for OLED applications.

Half-sandwich Ru(η-p-cymene) complexes featuring pyrazole appended ligands: Synthesis, DNA binding and in vitro cytotoxicity.

Organometallic Ru(II)-arene complexes have emerged as potential alternatives to platinum appended agents due to their wide range of interesting features such as stability in solution and solid, significant activity, less toxicity and hydrophobic property of arene moiety, etc. Hence, a series of Ru(II)-p-cymene complexes, [(η-p-cymene)Ru(η-N,N-L1)Cl]Cl (1), [(η-p-cymene)Ru(η-N-L2)Cl] (2) and [(η-p-cymene)Ru(η-N-L3)Cl] (3) were prepared from pyrazole based ligands [2-(1H-pyrazol-3-yl)pyridine (L1), 3-(furan-2-yl)-1H-pyrazole (L2) and 3-(thiophen-2-yl)-1H-pyrazole (L3)], and [RuCl-(η-p-cymene)] dimer. The new Ru(II)-p-cymene complexes were well characterized by elemental analysis, and spectroscopic (FT-IR, UV-Visible, H NMR, C NMR and mass) and crystallographic methods.

Biomolecular Interaction, Anti-Cancer and Anti-Angiogenic Properties of Cobalt(III) Schiff Base Complexes.

Two cobalt(III) Schiff base complexes, trans-[Co(salen)(DA)](ClO) (1) and trans-[Co(salophen)(DA)](ClO) (2) (where salen: N,N'-bis(salicylidene)ethylenediamine, salopen: N,N'-bis(salicylidene)-1,2-phenylenediamine, DA: dodecylamine) were synthesised and characterised using various spectroscopic and analytical techniques. The binding affinity of both the complexes with CT-DNA was explored adopting UV-visible, fluorescence, circular dichroism spectroscopy and cyclic voltammetry techniques. The results revealed that both the complexes interacted with DNA via intercalation as well as notable groove binding.

Evaluation of the Leaf Essential Oil from and Its Larvicidal and Repellent Activity against Dengue Fever Vector -An Experimental and Molecular Docking Investigation.

is a mosquito vector that spreads dengue fever and yellow fever worldwide in tropical and subtropical countries. Essential oil isolated from is found to have larvicidal and repellent action against this vector. The dried leaves were subjected to hydrodistillation using a clevenger-type apparatus for 4 h.

Water-soluble Cobalt(II) & Cobalt(III) complexes supported by new triazine Schiff base ligands: Synthesis, structure and biological evaluation.

A new class of triazine ligands (E)-2-(2-(6-methyl-5-oxo-2,5-dihydro-1,2,4-triazin-3-yl)hydrazono)propanoic acid hydrate (HL1.HO) and (Z)-2-(((E)-4-amino-6-methyl-5-oxo-4,5-dihydro-1,2,4-triazin-3(2H)ylidene)hydrazono)propanoic acid (HL2) has been synthesized by the condensation reaction of pyruvic acid with diaminoguanidine and triaminoguanidine respectively. The corresponding Schiff base cobalt complexes [Co(L1)]2HO (1) and [Co(HL2)(L2)].
