Summary: The study focused on the impact of molecular substitutions and isomerization on charge transport in organic semiconductor materials. It was found that increasing the length of silylethynyl substitutions can enhance the hole mobility of cis-isomer molecular packing. A favorable charge-transport material should possess an identical direction of induced ring currents and stable induced magnetic fields in their molecular packing.

Summary: This study reports the emissive properties of a heteroleptic cyclometalated Ir(iii) complex, which was synthesized and optically resolved using a chiral column. Two geometrical isomers were obtained and their molecular structures were determined using single crystal X-ray analysis. In the crystalline states, the intermolecular interactions influenced molecular packing, and when excited at 430 nm, yellow and orange emissions were observed for the different isomers.

Summary: The development of a new N-nitro type compound, dinitro-5,5-dimethylhydantoin (DNDMH), as an arenenitration reagent has been reported. The study demonstrated that arene nitration with DNDMH showed good tolerance towards diverse functional groups. Interestingly, only the N-nitro unit on N1 of DNDMH was delivered to the nitroarene products, while the N-nitro type compound with a single N-nitro unit on N2 could not promote the arene nitration reaction.

Summary: Complexes trans-[PdX2L2] (X = Cl and Br), where L is 1-(PR2),2-(CH=CH-C(O)Ph)-C6F4 (R = Ph, Cy, and iPr), exhibit phosphorescent emission in the solid state, while free ligands with shorter lifetimes display fluorescent behavior. However, derivatives with halide replaced by CN- or Pd replaced by Pt show no emission. DFT calculations reveal that only the hybridization of orbitals of the MX2 moiety with those of the ligand's chalcone fragment is significant for the LUMO of the emissive compounds, leading to observable luminescence.

Summary: A room temperature stable complex, Y(NHAr*)(2), was prepared through KC8 reduction of ClY(NHAr*)(2), where Ar* = 2,6-(2,4,6-(Pr-i)(3)C6H2)C6H3. Through EPR evidence, it was shown that Y(NHAr*)(2) is a d(1) Y(ii) complex with significant delocalization of the unpaired electron density from the metal to the ligand. Interestingly, Y(NHAr*)(2) reacts as a radical donor towards (BuNC)-Bu-t, resulting in the formation of an unusual yttrium isocyanide complex, CNY(NHAr*)(2), as supported by spectroscopic evidence and single-crystal X-ray diffraction data.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
