A family of CuI-based 1D polymers showing colorful short-lived TADF and phosphorescence induced by photo- and X-ray irradiation

Abstract

Exploiting 2-alkylsulfanylpyridines as 1,3-N,S-ligands, herein we have constructed 1D CuI-based coordination polymers (CPs) bearing unprecedented (CuI)n chains and possessing remarkable photophysical properties. At room temperature, these CPs show efficient TADF,...

Confinement of 1D Chain and 2D Layered CuI Modules in K-INA-R Frameworks via Coordination Assembly: Structure Regulation and Semiconductivity Tuning

“…Such underestimation is well documented and is caused mainly by the delocalization error of GGA functionals and the neglect of electron correlation effects . For CuI-based hybrid materials, large deviations at a similar extent have been reported for a number of compounds. , In addition, the Mott–Schottky test was performed on K-CuI-INA at 1000, 2000, and 3000 Hz (Figure S22). As shown in the Mott–Schottky plot, the C –2 value has a negative slope to the potential, while the intersection with the x -axis is independent of frequency.…”

Self-Assembly of an Anionic [Cu5I8]3– Supramolecular Cluster Driven by Ion-Pair Interaction and Catalytic Properties

“…High-nuclearity coordination clusters have attracted extensive attention because of their structural diversity − and wide-ranged application prospects in the field of photoelectron devices, − electrical conductivity, metal–organic catalysis, and fluorescent sensing. − As a common aggregate of copper­(I) atoms coordinated with halide anions, cuprous iodide clusters exhibited a variety of molecular arrays with rich electronic structures, including neutral, cationic, and anionic [Cu x I y ] x − y coordination moieties. − In the neutral cuprous iodide cluster aggregates [CuI] x , uncharged organic/inorganic ligands can support and stabilize the [CuI] x cores via Cu–N, Cu–S, or Cu–P coordination interactions, − such as Cu 2 I 2 rhomboid dimers, − Cu 3 I 3 trimers, Cu 4 I 4 cubane tetramers, , Cu 6 I 6 staircase hexamers, − Cu 7 I 7 pinwheel heptamers, − Cu 8 I 8 staircase octamers, and so forth. In order to construct ionic cuprous iodide clusters with high nuclearity, some cationic heteroleptic ligands were developed and reacted with copper iodide salt. − Up to date, it has rarely been reported for anionic cuprous iodide clusters, such as [Cu 4 I 6 (TPP) 2 ]­(TPP = alkyl-tris­(2-pyridyl)­phosphonium halides), [Cu 6 I 7 ] − , [L 4 (Cu 3 I 4 ) 4 ] 8+ , and so on .…”

Progress in the Field of Cyclophosphazenes: Preparation, Properties, and Applications

“…Due to their numerous potential uses in the fields of magnetism, optical, porosity, and catalysis, including conductivity, luminescence, non-linear optical materials, and coordination, polymers have received a lot of interest. Many novel structures are now accessible in the literature because of the recent amazing rise in the synthesis of CPs [ 39 , 40 , 41 , 42 , 43 , 44 , 45 ]. The metal/ligand stoichiometry, as well as the temperature and concentration, along with the kind of counter ion utilized throughout the reaction process, can all affect how the coordination polymers are made.…”
