Summary: The luminescent cyclometalated complexes decorated with cyanide ligand can serve as nucleophilic building blocks for halogen-bonded adducts, with noncovalent interactions playing a key role in their photoluminescent properties and excited states. The degree of aggregation via metal-metal interactions determines the optoelectronic properties and photoemissive characteristics of the crystalline materials.

Summary: The chemistry of (P,C)-cyclometalated complexes derived from naphthyl phosphines [(Np)(P,C)M] is reviewed and analysed in this paper. The three main synthetic approaches, P-chelation assisted C-H activation, oxidative addition and transmetalation, are described and compared. These complexes exhibit high thermal and chemical robustness, and have been shown to be competent catalysts in various transformations, as well as key intermediates in others.

Summary: Unsymmetrical dicarboxylato complexes react with different terminal alkynes to produce various compounds, and these reactions can undergo isomerization, annulation, reduction or coupling processes upon irradiation. The photoreactivity of these complexes is attributed to different excited states, and the products depend on the presence of electron-donating or electron-withdrawing groups on the alkynes. The C-C couplings from certain complexes are attributed to photoreactive pentacoordinate intermediates.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
