In the title compound, [Cu(C(14)H(12)N(2)O(4))(C(36)H(28)OP(2))]PF(6)·CH(3)CN, the Cu(I) ion is coordinated by two N atoms from the dimethyl 2,2'-biphenyl-4,4'-dicarboxyl-ate ligand and two P atoms from the bis-[2-(diphenyl-phosphino)phen-yl] ether ligand in a distorted tetra-hedral environment. In the cation, the short distance of 3.870 (4) Å between the centroids of the benzene and phenyl rings suggests the existence of intra-molecular π-π inter-actions.

On-site accurate and real-time monitoring of trace chemical warfare agents is a critical component of national security surveillance. In this study, a photoionization-induced chemical ionization time-of-flight mass spectrometry is developed for the detection of trace gaseous chemical warfare agents under ambient conditions. Firstly, a benzene-toluene-xylene mixture standard gas is utilized to optimize the instrument parameters, followed by screening of dopants for chemical warfare agents detection, with methanol ultimately identified as the optimal dopant.

The C-H functionalization of arenes mediated by well-defined bis(phosphine)-supported organometallic iron(III) complexes is described. One-electron oxidation of -(depe)Fe(CH) (depe = 1,2-bis(diethylphosphino)ethane) generated the corresponding isolable iron(III) dimethyl derivative that was unstable toward Fe-CH homolysis. Oxidation of the corresponding iron(II) bis(aryl) complex -(depe)Fe(tolyl) resulted in rapid reductive elimination of the biaryl with formation of iron(I).

We report the design and synthesis of two novel phenanthroline-based ligands, a catechol-functionalized derivative (: 4,7-(4-catechol)-2,9-dimethyl-1,10-phenanthroline) ligand and its methoxy analogue (). These ligands were used to prepare four Cu-(I) complexes: two homoleptic bis-diimine Cu-(I) complexes ( and ) and two xantphos-based heteroleptic diimine-diphosphine derivatives ( and ). Their photophysical and electrochemical properties were characterized by steady-state and time-resolved spectroscopy, cyclic voltammetry, and density functional theory (DFT) calculations.

In the field of advanced electrical energy conversion and storage, remarkable attention has been given to the development of new, more sustainable electrolytes. In this regard, the combination of redox shuttles with aqueous bio-polymer gels seems to be a valid alternative via which to overcome the typical drawbacks of common liquid electrolytes such as corrosion, volatility or leakage. Despite the promising results obtained so far, redox-active species such as bis(6,6'-dimethyl-2,2'-bipyridine)copper(I) trifluoromethanesulfonylimide, ([Cu(I)(dmby)]TFSI), still present inherent challenges associated with their poor water solubility and oxidative lability, which prevents their employment in cheap and sustainable aqueous electrolytes.
