Synthesis and Reaction Chemistry of Zinc‐Diarylphosphido Clusters with Phosphorus Precursors

Abstract

The synthesis of the zinc phosphido clusters [Zn 2 -(μ-PPh 2 ) 2 (PPh 2 ) 2 (NC 5 H 5 ) 2 ] (1) and [Zn 4 (μ-PPh 2 ) 4 (OAc) 4 (NC 5 H 5 ) 2 ] (2) is presented. The clusters are accessed via the reaction of Zn(OAc) 2 with differing amounts of Me 3 SiPPh 2 . When 1 was heated under solvothermal conditions in pyridine, it yielded micrometer sized metallic zinc crystals via the reduction of Zn II by the diphenylphosphido ligands, forming tetraphenyldiphos- [a]

Elucidating the Phase Transformation and Metallization Behavior of Zinc Phosphide under High Pressure

“…For example, it has an absorption coefficient of greater than 10 4 cm –1 , a direct bandgap of ∼1.5 eV, and a long carrier diffusion length of ∼10 μm. − In addition, Zn 3 P 2 has a high natural abundance, economic and environmental friendliness, and ease of fabrication. These favorable properties firmly position Zn 3 P 2 for a wide range of applications as a semiconductor for large-scale photovoltaic applications; it also has been explored as a p-type absorber, light-emitting diode, and lithium ion battery. − More importantly, Zn 3 P 2 has been proposed as a candidate material for low-cost and high-efficiency next-generation solar cells. , Many studies have been devoted so far to intensively investigate the physical and chemical properties of Zn 3 P 2 at ambient conditions theoretically and experimentally, − with only a few investigations related to its structural stability and electrical properties under extreme conditions, which limits the further applications of Zn 3 P 2 .…”
