- The pursuit of p-type semiconductors has garnered considerable attention in academia and industry. Among the potential candidates, copper iodide (CuI) stands out as a highly promising p-type material due to its conductivity, cost-effectiveness, and low environmental impact. CuI can be employed to create thin films with >80% transparency within the visible range (400–750 nm) and utilizing various low-temperature, scalable deposition techniques. This review summarizes the deposition techniques for CuI as a hole-transport material and their performance in perovskite solar cells, thin-film transistors, and light-emitting diodes using diverse processing methods. The preparation methods of making thin films are divided into two categories: wet and neat methods. The advancements in CuI as a hole-transporting material and interface engineering techniques hold promising implications for the continued development of such devices.

- The paper presents the fabrication and characterization of [CuI(L)]n thin films, where L represents various alkylpyridine ligands including 4-methylpyridine, 3-methylpyridine, 2-methylpyridine, 4-tbutylpyridine, 3,4-dimethylpyridine, and 3,5-dimethylpyridine. The thin films were synthesized by exposing the corresponding ligands to CuI thin films through vapor deposition. The coordination reactions occurring on the films were investigated using PXRD and time-dependent photoluminescence spectroscopy, and a comparison was made between the structures of the thin films and the corresponding powder phases. The films showed primarly blue emission (λem = 457–515 nm) and polymeric structures with excited state lifetimes ranging from 0.6 to 5.5 μs. Significantly, the studied compounds exhibited fast reversible luminescence quenching when exposed to vapors of dichloromethane and dibromomethane (15 and 30 min respectively), and the luminescence was restored upon re-exposure to the alkylpyridine ligand (after 20 min). These findings indicate that these thin films hold promise for applications as sensors (with sensitive and reversible detection capability) for volatile halogen-based compounds (VHC).

- The current paper describes the formation of a new series of platinum(II) complexes with 5,7-di-tert-butyl-2-(thiophen-2-yl)benzo[d]oxazole (btbo) ligand. This study has focused on synthesis methods of some organoplatinum(II) complexes containing btbo ligand from two different reagents under different conditions. Furthermore, a detailed computational study was performed to identify the thermodynamic parameter's behavior. The synthesis was initiated from some complexes including cis-[PtCl2(dmso)(2)], R1, [PtCl2(COD)], R2 and a benzoxazole derivative as organic ligand 5,7-di-tert-butyl-2-(thiophen-2-yl)benzo[d]oxazole, (btbo). Implementation of the H-1 NMR analysis procedure on products reveals two isomers' existence. Moreover, the thermodynamic parameters, (Delta H degrees, Delta G degrees, Delta S degrees), were quantified to achieve a more precise understanding. The energy diagram examination and considering the quantified parameters present the stability and instability of each product which is in notable agreement with the experimental data.
