All-in-one: a new approach toward robust and solution-processable copper halide hybrid semiconductors by integrating covalent, coordinate and ionic bonds in their structures

Abstract

Conventional inorganic semiconductors are best known for their superior physical properties and chemical robustness, and their widespread use in optoelectronic devices. However, implementation of these materials in many other applications...

Two-Dimensional Copper Iodide-Based Inorganic–Organic Hybrid Semiconductors: Synthesis, Structures, and Optical and Transport Properties

“…The significantly enhanced stability of these structures is due to the formation of higher dimensionality as well as the use of ligands that form strong Cu-N bonds. 21,23 Electronic Structures.…”

“…Copper iodide based crystalline inorganic-organic hybrid materials have attracted great attention in the recent years due to their structural diversity and unique optical properties, which demonstrate strong potential for general lighting related applications. [12][13][14][15][16][17][18][19][20][21] Several types of structures with different inorganic building motifs have been developed, and intensive studies have been carried out to improve their optical properties and chemical/thermal stability. [22][23] However, investigation of their electric properties as EL materials remains underexplored.…”

Structural characterization and luminescence properties of trigonal Cu(i) iodine/bromine complexes comprising cation–π interactions

“…The coordination number of the Cu(I) center is successfully reduced to three because of strong coordination ability and appropriate steric hindrance of the ligand together with Cu-p interactions. Quite remarkably, the trigonal planar Cu(I) complexes not only afford emission at low energy (4600 nm) but also exhibit high PLQYs of 65% (1) and 72% (2). Consequently, these observations provide a new insight for molecular design of Cu(I) complexes for efficient luminescent materials.…”

“…Copper(I) halide complexes have attracted a large amount of attention as a new class of promising emissive metal complexes due to their rich structural diversity, outstanding photophysical behavior and relatively low-cost compared to their noble metal counterparts. [1][2][3][4] In particular, high photoluminescence quantum yields (PLQYs) approaching 100% are possible for the Cu(I) complexes as no internal quenching processes of excited states via low-lying metal-centered d-d* states take place in contrast to other 3d element (Ru II , Pt II and Ir III ) compounds. [5][6][7] Previous reports have indicated that Cu(I)-based complexes with different types of coordinated ligands are able to achieve remarkable luminescence characteristics, including room temperature phosphorescence (RTP) and thermally activated delay fluorescence (TADF).…”

Highly Luminescent Copper(I) Halide Phosphors Encapsulated in Fumed Silica for Anti‐Counterfeiting and Color‐Converting Applications

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] Owing to the rich coordination chemistry of Cu(I) ions, their combination with organic and inorganic ligands often leads to a large structural diversity, ranging from discrete molecular 0D to 1D chains, and from 2D layers to extended 3D networks. [14][15][16][17][18] Generally, luminescent Cu(I) hybrid materials can be synthesized via the reaction of CuX with organic nitrogen, phosphorus, and sulfur ligands in organic solvents. [19][20][21] The inorganic and organic components may connect via covalent bond, ionic bond, or coordination action.…”
